Re: How to Mix IPA for Inspecting Correction Results
Wow, great article. I too have used 70IPA right out the bottle onto a rag to wipedown heavy compounds. Most of my polishes are pretty easy to just wipe off with a towel, but some of the compounds don't want to come off. I never considered 70IPA to he a hot solvent, but I guess you learn something new...
I only read the first couple pages, but have you tested any other solvents or asked you chemist buddies about them? I work with clear coats in other areas of work and deal with them fresh and cured, and in the shop we have various solvents and the only one we use on paint undiluted is Naptha. 100% pure poured onto a rag and wipe down(it is a 3 stage Dupont solvent based clear and we use it on custom pool cues). We also use Denatured alcohol, laquer thinner, mineral spirits and acetone. Acetone being the hottest and Naptha being the mildest. Naptha and acetone have low boiling points so naturally they dissipate quicker at room temps than alcohols.
One thing I would like to know is if Denatured alcohol would be better/safer for auto paint than IPA? I'm guessing it is just from my experience with it. It would need to diluted as the IPA or maybe more so, but I feel like it would make a better weak cleaning solvent than IPA. I guess I'll go back read through the entire lost to make sure I didn't miss you testing other solvents, it if you haven't, might be a goodbthread for some testing. Great website with lots of good information.
Thanks

Re: How to Mix IPA for Inspecting Correction Results
So I did a little digging into the products I've been using for years and thought I understood pretty well. Turns out I didn't. Naptha is apparently "Hotter" than mineral spirits, but more volatile and faster evaporating. Not sure which would be better for cured paint, but I've been wiping 100% Naptha straight onto paint for quite a while with only positive results. I would be afraid with Mineral Spirits. I've also been wiping 70% IPA like and idiot onto cars, and thanks to this article I won't do it again. Mike, you may have literally saved me 5000. One of my customer owns a Bentley and so far I have only used finish polish and wax on it, but I know one day it will need something stronger, something that a solvent will help wipe away. Now I know what to do.
As for denatured vs IPA, they turn out to be somewhat similar. The differences I can tell is that IPA is cheaper, easier to get pure and probably mixes better with water at any strength. But IPA is also "hotter" and less volatile. IPA will stay on the paint longer, evaporating slower than Denatured alcohol. Denatured is actually ethanol like we drink mixed with methanol or IPA or MEK (now that was a good solvent that I can't seem to find anymore anywhere) or whatever else they have handy that will make it non-potable. So if you want to use Denatured over IPA as will probably end up doing when I figure out what mix to use, shop around and see what they used to "Denature" it. I read some guys saying that the "green" version are good and have high ethanol concentrations.
Mike, see if you can get a rundown on all these widely available solvents from your chemist next time you talk to him.
Again, an awesome article that will help lots of people.
Thanks

Thanks but just to note, as I point out in the first post of this thread I was never really interested in writing this article.
I even asked for volunteered to write it but no one ever stepped up to the plate.
The problem was there was a few guys back a few years ago that were telling everyone to strip their paint with IPA but that's as far as it went. They gave no details, no warnings, just their normal one-liners.
So in an effort to help prevent people from making mistakes, scratching their paint and to simply bring some common sense about this procedure I broke down and wrote the article.
This was also years before we had products like Erasure, Panel Wipe and BLACKFIRE Crystal Coat Paint Prep.

Agreed. Ever since I started using Eraser I'v never gone back to IPA or using Mineral Spirits.
Detailing technology has rapidly evolved over the last few years with MANY advancements.

I've seen paint wrinkled from exposure to strong IPA and it's not a comfortable sight.
I leave it in the spray bottles as we use it up fairly regularly for all kinds of things.
I always recommend following the manufactures advice as they tend to know their products and processes best.
Thanks for chiming in, I do appreciate hearing what other chemists have to say on the topic and I agree it seems to be a topic that can get some people kind of emotional...
I prefer how MS wipes over paint as compared to IPA but either way, when IPA is diluted with water it wipes a lot better then the stronger versions straight out of the bottle.
One thing for sure, while Isopropyl Alcohol is a liquid, that doesn't automatically make it a great lubricant and from my testing on clear coated black paint, it's pretty hard to wipe a highly polished black finish and not detects some marring from the wiping process.
The point of this is that if it's happening to a clearcoated black finish and it's pretty easy to see, it's likely happening to a finishes but it's going to be more difficult to see on lighter colors like silver metallics, etc.
So like you're doing, anyone else doing this should try to use, clean, soft microfiber towels and a gentle touch...

Hi Mike,
I would like to know what do you think about the product DupliColor Prep Wipe PW100, since here in Mexico it's difficult to get some good product or they are expensive and I think it this towels could l be a good option, although I made my IPA mix too, with 15% IPA (IPA @ 99% pure) and 85% Distilled water, so I don't know which will be better, to get the PW100 towels or stay with my IPA mix.
Here is the MSDS, it uses Mineral Spirits and other thing.
Thank you for your knowledge
Alex

Hi Alex,
Sorry I just now found this question....
As long as you're working on cured and/or factory paint I think the two options will work fine.
