    Certainly having chemically clean paint allows sealants to bond better, thereby increasing their longevity; in fact it's a must with some nano sealants.

    I'm the first to admit that I can be a little anal when it comes to prep, but I've never thought of that as a bad thing tbh.


    I'll just stick with what I originally wrote, which is targeted at traditional car waxes and synthetic paint sealants, not paint coatings.


    Miscible and Immiscible - Wax and Paint Sealant Bonding


    Sheldon explaining Quantum Physics to Penny on the Big Bang Theory



    Wax and Paint Sealant Bonding
    The topic of bonding as it relates to a wax or a paint sealant bonding to paint comes up on most detailing discussion forums from time to time, and there's a lot of confusion and probably miss-information about this topic.

    The idea presented is that in order for a wax or paint sealant to properly bond to an automotive paint finish, the paint finish must be chemically stripped so that the paint is surgically clean and free from any residual polishing oils or any other substances.

    The goal is to insure there's nothing on the surface that could potentially interfere with the bonding action between the protection ingredients in a wax or paint sealant and the paint.


    Follow the Manufacturer's Recommendations
    The first and primary consideration goes to the manufactures recommendations. If the manufacturer of a wax or paint sealant officially recommends that the surface of the paint must be stripped clean before their product can properly bond to the paint, then you should follow the recommendations of the manufacturer as they know their products best.

    If the manufacturer does not specifically recommend that a painted surface needs to be stripped clean, then whatever recommendations they do provide should be followed as they know their products best.

    To my knowledge, there are only a few manufacturers in the wax and paint sealant business that recommend that the surface of automotive paint be surgically clean and bare before their products can be applied. Besides these few companies, most manufacturers either recommend to apply their wax and/or paint sealant to the paint after first using their surface prep products which can include, compounds, polishes, paint cleaners and pre-wax cleaners. And of course, sometimes there are no specific recommendations.


    Back in February of 2005, this topic came up when I worked for Meguiar's as it related to applying NXT Tech Wax over a surface previously polished using Meguiar's M80 Speed Glaze.

    Here's the specific thread,

    Do Glazes/Fillers affect the bonding of NXT?


    I contacted R&D, communicated with one of the Chemists, and then posted a statement provided to me on this topic.


    A wax, (natural or synthetic), is a substance that when applied to a surface will not adhere properly on its own. Thus, it is necessary to add specialized miscible oils to allow the waxy material to spread and adhere evenly to the surface. These oils along with polymers are responsible for improving the functionality of the wax protection, appearance, adherence and the overall application.

    This means the addition of any Meguiar's polishes prior to the wax application will not only enhance the paint finish, but also aid in the appearance, adherence and overall lasting ability of the wax which is applied over the top of it.

    Since leaving Meguiar's and joining the Autogeek Team in 2009, the topic of bonding has come up from time to time. I knew I had written on this topic, but could not remember the keyword or words to help me locate the above thread. Then I remembered the word, did a search and found the thread.

    Here are the key words, and note the portions I've formatted to be bold, red and italic...
    Taken from TheFreeDictionary.com

    Miscible
    Relating to two or more substances, such as water and alcohol, that can be mixed together or can dissolve into one another in any proportion without separating.


    Immiscible
    Incapable of being mixed or blended together. Immiscible liquids that are shaken together eventually separate into layers. Oil and water are immiscible.
    I'm not a chemist and don't ever claim to be one and do everything I can to avoid talking or typing over my head. That said, it is my opinion that while the above information is supplied by a chemist at Meguiar's, it's probably true for most quality waxes and paint sealants manufactured by reputable companies, unless they state otherwise, i.e., unless they state that the surface must be stripped clean before applying their wax or paint sealant.


    So unless a manufacturer specifically states or recommends that an automotive paint finish must be stripped clean for their wax or paint sealant to properly bond or adhere, then I think it's safe to say that the chemist behind the brand has created their wax and paint sealant formulas to use the same miscible oils, (or other miscible substances), in their surface prep products to aid in the bonding or adhering of the protection ingredients used in their waxes and/or paint sealants to paint.

    This would be called, Synergistic Chemical Compatibility.


    It's entirely possible that a lot of popular waxes and paint sealants on the market will bond or adhere to paint correctly after the paint has been prepped using compounds, polishes and paint cleaners outside the brand of the waxes or paint sealants being applied. There's no easy way of knowing or testing, but in my opinion, I would think the chances for this type of chemical compatibility to be more likely than less likely as there is probably some common chemistry involved in surface prep products and protection products that overlaps among different polish and wax companies.

    That's just my opinion or guesstimate, you can make up your own mind.

    My good friend, Tom aka Mosca as he's known on detailing discussion forums, once posted,

    Quote Originally Posted by Mosca

    I would have to agree with Tom.


    To strip or not to strip?
    Do you need to chemically strip your car's paint with some type of solvent before applying a wax or paint sealant to enable the protection ingredients to better bond or adhere to the paint?
    Manufacturer's Specific Recommendation
    Only if the wax or paint sealant manufacturer specifically recommends this procedure.
    Or
    Personal Preference
    If after researching this topic you personally want and feel the need to chemically strip the paint.
    Or
    Forum Member's Recommendation
    See what I wrote above under Personal Preference
    If you use good quality products and follow the manufacturer's directions, plus work clean and use good technique, then you should be able to apply your choice of wax or paint sealant directly to your car's paint after wiping off the residue left by the last surface prep product used on the paint. This, by the way, is my normal practice, and below is my personal recommendation on this topic as taken from here.


    How to Mix IPA for Inspecting Correction Results


    Excerpt

    To remove any previously applied wax or paint sealant, I recommend using a light paint cleaner or a light polish applied by hand or machine. A light paint cleaner or abrasive polish will effectively remove any previously applied wax or paint sealant AND leave the paint looking clear and glossy. I call this working forward in the process because the goal is to create beauty.

    Chemically stripping the paint will tend to dull the paint; it certainly doesn't increase gloss and clarity. You don't see the dulling effect unless you're working on black paint and repeat the process multiple times. Since not everyone works on black paint, and you're not going to make stripping your car's paint a daily routine, it could be you won't see the dulling effect on your car's paint but it does take place.

    Wiping a clear coated black finish over and over and over again with any type of solvent isn't going to make the top clear layer of paint more and more clear, it's going to do the opposite, that is dull it down.

    So chemically stripping paint is what I call working backwards in the process. I, personally, prefer to work forwards in all my detailing projects but do understand the reasons why some people want to chemically strip their car's paint, or their customer's car's paint, and each person can decide what the best approach is for their needs.

    And again, since you're not chemically stripping the paint as a "practice" but only during a detailing session, the dulling effect is not an issue, but I wanted to point it out just for the most detail oriented detailing enthusiasts or Pro Detailers reading this article.

    Re: Miscible and Immiscible - Wax and Paint Sealant Bonding

    its certainly an interesting read, but as i have said before, i believe there are significant differences between waxes and sealants that are being overlooked. In point of fact, the statement made by the meguiars chemist refers only to waxes, he makes no mention of bonding with sealants whatsoever. The assumption appears to be that what's best for one, is best for both, and that simply may not be the case. Added to which, manufactures aren't going to worry if their product doesn't last quite as long as it might. They want buyers to have everything looking shiny for very little effort, because thats what sells products. So they're not going to discourage anyone from using polish under sealant unless there is a significant risk of product interference, it really wouldn't be in their best interests. Quite the opposite in fact. I look on it like this, a chain is only as strong as its weakest link, and in the case of sealant over polish, that would be the polish. it's just not designed to last as long as a sealant, if it was, you wouldn't need sealants at all.
    Also, being miscible only means that the polish and the sealant bond well to each other. It does not mean that they will bond as well to the paint surface when combined as the sealant would do on its own. in fact, a layer of polish that has been buffed to a finish could form a barrier preventing the sealant from bonding to the paint at all. this means that the sealant is then only attached to a weak layer of polish that will degrade relatively quickly.
    will it look better? probably yes, because you're hiding faults in the paint. And to my mind, that is where the compromise is; polish more comprehensively, or disguise the damage with fillers and accept a weaker bond with the sealant. sometimes the latter is the only option, but in principle at least, i believe the former to be fundamentally better when it is practical to do so.
    i suspect that we shall have to agree to disagree, but perhaps you can begin to understand why there are two very different schools of thought on the subject.
    kind regards

    The only time I have been wiping cars down to prep the surface is for paint coatings like Opti-Coat and CQuartz, which is actually recommended by those manufacturers.

    Same here. If I am waxing or even using a sealant such as Menzerna Powerlok, my last step is to wash the vehicle to remove all the dust. Other than that, I do not chemically wipe down the car. If I am doing a coating, yes.

    I have never had an issue doing this.

    Me begin to understand?


    I completely understand, heck I write articles on these topics so other people can understand....


    I just think it's all to easy for people to take things that are very simple, like washing and waxing their car, and make it as complicated as possible. Nothing wrong with that if that's what a person wants to do. Me? I like to keep things as simple as possible.

    Instead of chemically striping paint just to apply a wax or sealant to try to eek out a little more time before it completely wears off I'll simply re-apply. Kind of like changing the oil in the engine in my truck before it breaks down 100%

    I have done my own testing will sealants "bonding" and glazes. I can tell you a glaze does not really affect a modern sealant's chemical resistance. In fact, many sealants today recommend using a paint cleaner that contains a glaze component to prep.

    I don't think it's as difficult for sealants to last the duration as some may think...It doesn't need to be overthought. Ever try to get a sealant out of a foam pad? It's like impossible. If the sealant is quality - it will be equally as hard to get it off your paint. APC & IPA can't even dissolve a sealant. I wouldn't worry about a micro amount of polishing lubricants.

    It just works.

    Chemically stripping a polished car with Eraser or similar prior waxing is a waste of time & product IMHO. Wax doesn't "bond" - it's just sits there like an oily residue. I do not believe "polishing artifacts" on otherwise clean paint affect the durability of wax by one minute. Any polishing residue will be removed by the solvent in the wax - which all wax must contain.

    IMHO you would be better served just wiping each panel down with a waterless wash or similar as you go along to make sure the panel is surgically clean (particle free) and dust free before slathering wax all over it with an applicator. That is what I focus on - cleanliness.

    Stripping wax every time you want to top if off or renew it is just crazy. Just wash the car, wax it, and be done with it. Yes, it should be stripped down every once in a while - what defines "once in a while" will be different for each vehicle. I usually go about 5 months.

    Re: Miscible and Immiscible - Wax and Paint Sealant Bonding

    On the topic of preventative maintenance....

    Changing the oil every 3000 miles is a common practice called Preventative Maintenance, the idea being to change the oil BEFORE it's so far spent damage can occur to the motor parts.

    If we apply that to washing and waxing our cars.

    We wash our cars regularly to not only keep them shiny but to prevent the build-up of dirt and road film, which attracts moisture and then the entire matrix of stuff on the car's exterior would go to work deteriorating it.

    We re-apply a car wax or synthetic paint sealant before every trace of the last application is scientifically documented to be gone because it's good preventative maintenance.

    I think I talk about that here,

    Sacrificial Barrier Coating = The purpose of a wax or synthetic paint sealant


    Here's a small excerpt from the above article,




    Two extremes and people in-between
    How often you need to apply a coat of wax or a paint sealant is a personal decision that only you can make. That said, there are two basic categories of car waxers... the Minimalist and the Maximallist, and a third catagory... everyone in-between...


    Minimalist
    My guess is a minimalist is more than likely going to be the type of person that looks at their car as a means of transportation. Wax your car 1-4 times a year. This would be a benchmark number for the minimum number of times you can wax your daily driver and expect the paint to hold up over the service life of the car and for it to look good to some level. Assuming your car is a daily driver, parked outside, then waxing your car just one time a year won’t probably maintain your car’s finish to show room new condition but everyone has their own standards and expectations so find a routine that works for you.


    Maximallist
    My guess is a maximallist is more than likely going to be the type of person that looks at their car as an extension of their personality. This type of person usually doesn’t need anyone telling them how often to wax their car because they already wax their car often. They wax their car often to protect and preserve the paint but just as important to them is to make the paint and by default, the car look good.

    In-between
    My guess is that waxing your car is something that never makes it on to your "A-List" of projects and probably not even your "B-List" of projects. It probably gets done by you or someone, it's just not a priority or your passion.


    Oil Change
    Whether you’re the Minimalist or the Maximallist, or someone that falls in-between, here’s a better method to the madness as to determining when or how often to wax your car, two words… Oil Change

    No I don’t mean wax your car every time you change your oil, what I mean is think of waxing your car in the same way you think of changing your oil. Here’s what I mean…


    PM = Preventative Maintenance
    Most people change their oil every 3000 miles as that is what the manufacture recommends to prevent pre-mature failure of the moving parts inside the motor. The motor won’t blow up at 3001 miles as going past 3000 miles doesn’t mean the oil is no longer lubricating the moving parts, it’s a Preventative Maintenance Practice.

    The idea being to remove the old, worn out oil BEFORE it’s so worn out that damage can occur. This approach to engine maintenance works and millions of miles on millions of engines documents this practice.

    Now take that same idea and apply it to waxing your car’s paint… that is re-apply a fresh coat of wax before all of the last coating has completely worn off. Apply a coat of wax BEFORE there is so little protection left on the surface that damage can occur.

    If you car is in fact a daily driver, then a good minimum number of times to apply a coat of wax to your car’s finish to insure that it’s fully protected against attack would be 4 times a year, that's once every 3 months.

    In a perfect world, if you have the time and inclination, then waxing more often certainly won’t hurt anything, you can decide how often for yourself. I put a coat of wax on my daily driver truck at least once a month. For me it’s different than it is for others because I work in the car wax industry… I usually have a new wax to test often enough, or a new wax I’m curious about that it’s just so easy to go out into the garage and apply a coat of wax. So don’t use me as a benchmark…

    All valid arguments. However, what would you say about coatings like Modesta that have their own primer polish, which can be used prior to applying one of their coatings, which claim 3-10 years durability? Or Optimum Opti-Coat Pro, which requires you to use their Primer Polish prior to applying their coating, which is permanent? On top of that, Optimum has said you can coat right over any other their polishes, and only wiping down with a damp MF towel is needed prior to application.

    I don't think Meg's chemists are offering any advice about traditional "waxes" (non polymer or hybrid LSPs) - since they don't make any.

    All their products are sealants.

    Meguiar's M26 High Tech Yellow Wax - a premium yellow Carnauba wax blended with silicones, polymers and other waxes.

    Gold Class Carnauba Plus - a special blend of premium Carnauba plus clear coat safe protecting polymers.

    These are both "traditional waxes" containing Carnauba, polymers and other waxes, IOW, hybrid LSPs.
