The rubber seals of my 2006 Sentra are breaking down. Last 3/4 years I have been trying various products to clean, protect, maintain those seals but none seem to be working. Many of these products have been quoted here on the board so I don't know what I am doing wrong. The interior seals are not brittle but the outside ones are not in good shape. Some are brittle and falling apart.
The rubber seals around the trunk leak that in the middle of the winter the spare tire is frozen in ice. I can not find where it is leaking from.
The sunroof seals of the Forester have turned spotty white but they don't leak yet. Some pictures for reference.
This is vinyl trim

Feel like the rubber on the ends is breaking apart (but is not brittle, yet)

Spotty rubber (Forester's sunroof seals look pretty similar)

This rubber seal was softer but now it is hard and brittle.

My questions -
- Do folks on this board use term the seal and trim interchangeably? To me, the trim is the plastic/vinyl component outside and the seal is the one that actually seals (wind, water etc) inside and outside the vehicle. While going through older threads, I felt it has been used interchangeably so wasn't too sure if the product claimed for the trim can also be used for the rubber seals on the doors, windows, the trunk or the sunroof.
(Pls correct me if I am wrong in my trim/seal understanding.)
- To clean the rubber seals, I have used carwash soap, APC (but not dish soap) with the toothbrush and I have not been able to clean those seals very well. This year esp, they are pretty bad due to the pollen fixing their place in the crevices (esp for Sentra with its crappy design). What other option do I have?
- Is there a significant difference between the products made for RV/Marine and for regular auto use? For example, while searching for Meguair's M39 and M40 mentioned on one of the threads, I came across Meguiar's(R) Marine/RV Vinyl and Rubber, Cleaner & Conditioner, 16 oz. (https://www.meguiarsdirect.com/meguiars-marine-rv-vinyl-and-rubber-cleaner-conditioner-16oz.html) To me, this looks like an AIO, cleans as well as protects rubber and vinyl. I didn't find this product mentioned on the board. If this is not suitable one, is there any other AIO product that will not only clean but protect the rubber seal as well.
Thanks in advance.
Good question on whether the folks here use the term seal and trim interchangeably, so I am subscribing to hear that answer.
As far as what I have done is the "trim" I clean and treat twice yearly, first by using Mother's Heavy duty trim cleaner, and follow that up with Wolfgang Exterior Trim Sealant (actually will be looking at a trim coating soon, as I would rather only have to do this once a year).
In regards to the seals, there are a few places on my wife's Escape that no matter what I do, I can't seem to get rid of the discoloration you mention.
With that said, all my pieces of trim get 303 Protectant, in order to keep them from getting brittle. Also helps them from freezing shut during the winter. My reason is that really don't care what they look like; more important to me is to keep them in good shape.
I'm sure more definitive answers will come. I have never had an issue of water getting in my trunk down into the spare. My DD is a 2009 Yaris, and the only issue with the trunk seal is it being pulled off when pulling 2x4s out after visiting Home Depot ;)
Good luck...Eric

Im a mechanic for a living so ill break this down how it comes to me. I consider trim to be the textured plastic, and the rubber that surrounds the windows when rolled up. I consider seals to be the rubber that is inside the doors when they are closed along with the trunk. for my trim I like WETS, for seals I have not had to apply anything to mine, but 303 makes a rubber seal conditioner and protectant. If its anything like their other products im sure its amazing. I have honestly never picked up a 303 product I wasn't happy with.

For the trunk lid rubber seals and door and door jambs and the hood rubber seals. Get you a bottle of 303 Rubber Seal Protectant. Not just very effective during the winter months when these can freeze. But also rejuvenate the rubber seals in a way I didn't think was possible. A good friend of mine had a Chevrolet Caprice 4doors HT '70 and if not the original then very old rubber seals. They had started to fall apart and you couldn't wipe with a mf towel on them as you where catching on to the old rubber and it would break even more. This also creates a high wind noise from them on a HT. So tried to clean them as good as possible with almost just dabbing when cleaning them. And just for fun and see if it did something to these rubber seals as he was going to be buying new ones. I applyied the 303 Rubber Seal Protectant in 2 layers as they soaked it up fast. Let it dry for a few hours with the doors opened. The next day I drove it back to him and it where almost no wind noise from them at all. There where 2 places where the rubber seals was broken off. And what we could hear it where only the wind noise from those places. Don't know how how it works on the outside of the rubber seals. But there I would try the 303 Aerospace Protectant instead. So I got to be a believer in the 303 Rubber Seal Protectant to say the least LOL.

Plastic is trim for me and rubber is seals. Then you have some car modells that have rubber trim instead of plastic trim. The rubber trim has no seal ability. One thing that you useally have on rubber seals is holes in them that the rain water and the air gets in and out. Especially on the trunk lid rubber seals these can be sealed with dirt. So cleaning them good with cotton swab or needle if necessary so they are open always is important to check yearly. Also the door rubber seals you get to lay you down on the ground with the door opened and look so these holes in the rubber seals is open is good to look up. As it's around all plastic trim and rubber seals outside of the car that dirt build up don't have happened. There the rain water and also leftover rinse water from washing can be standing in these parts. Compressed air to blow out the dirt when it's dry and then long bristle brushes to really get to reach deep to clean them up. You can have rain channels that can also be shut with dirt. That can lead to the leak into your trunk for an example. Also it's not unusual on older cars that around windows you can have a rust problem under the rubber seal. This if you have it on the back window and also on the back side windows can leak into the trunk. And look at the spare tire compartment if you have some kind of rubber seals in the bottom that should be letting out the water that can be filled or covered with dirt.

Now that we are on the same page with regards to the trim and seals, I would like to focus on the rubber seals. The primary reason is to prevent them from freezing shut in winter.
For the last 3 to 4 years, I have been washing/cleaning the rubber seals with diluted car wash soap or diluted APC (Super clean 1:4) in a spray bottle. After drying, I apply 303 Rubber protectant or some silicone products to avoid the freezing part. None of that has helped. So my guess is, there is a problem with my cleaning process. Probably, I am not able to clean it well hence not getting the effect of the products that work with others.
How would you recommend me to clean them? I don't have access to a pressure washer or compressed air. There is a TON of dirt under the seals but on the seals as well. I won't be able to remove the dirt underneath without pulling the seals out, which I don't want to do, but I would like to clean them where they meet the door. Which products would you recommend me to give a try?

This thing seems to have same material as dielectric grease, so I plan to give a try to that this year after I manage to clean the seals up well.
This is a sedan so the rain channels are pretty much outside and clean, but being parking under the sky doesn't take long to gather leaves there due to the design. I also checked the trunk seals yesterday but didn't find any holes on them. A couple of years ago, the mechanic drilled a hole in a spare tire area and asked me to remove the grommet once in a while to drain out whatever is collected. His suspicion is, the leaves and twigs that gather in the rain channel overflow and that drains water in the trunk.
So in the end, which products would you recommend me to use to clean the rubber seals? I have Mother's VLR, 303 Aerospace Protectant (White spray bottle) and 303 Rubber conditioner and protector. Not too sure if any of these have cleaning properties. Hence, I linked that Marine cleaner and conditioner in the OP. But if there is any dedicated rubber cleaner that you prefer, I would love to know.
Thanks again for all comments/suggestions.

Interesting...With the seals that I was experiencing issues with, just a quick wipe down with my usual APC, followed by 303 Protectant got rid of my freezing issue.
This is in the Northeast...wondering where you are located. Doesn't sound like you are doing anything wrong with your process of cleaning, but I don't have experience with the products you used.
However, I was ready to purchase the Nextzett product you mentioned, if the 303 didn't work; have read alot of good things about it here and elsewhere (think it was recommended on the VW Vortex forum that I visit, since the car suffering the issue is a 2016 Tiguan R-line).

I have used Gummi Pflege on all of my rubber seals since my truck was a year old.
They still look new, and I have never had issues with them freezing.
I use the Gummi Pflege a few times a year, but right before it starts getting really cold, I use it at every wash (once a week) to get a good build-up. :)

This is for 2006 Sentra. The rubber seals, by design, are exposed to the roof. My suspicion is, the rubber has aged and as a result, no matter what I do, there is water seepage in the fine gap that is there. (Plus, the car is not garaged.) My feeling is if I do manage to get that rubber cleaned up well and condition it often till Christmas, hopefully, it should alleviate the problem in the peak season. That is the reason why I am looking for a rubber specific cleaner.
I do not have this problem in another vehicle, where the rubber seals are not directly exposed to the roof.
@Eric, I am in NYC suburb too, little north.
I believe Gummi Pflege is dielectric grease + something else. Don't remember MSDS anymore.

•P21S Total Auto Wash (TAW) is excellent
at cleaning/prepping EPDM-“rubber”
seals/weatherstripping.
•After cleaning, it’s:
-Gummi Pflege.
-Gummi Pflege is great stuff, IMO.

Sounds like this is the seal you are talking about: Roof & Components for 2006 Nissan Sentra | Nissan OEM Parts Now (https://www.nissanoempartsnow.com/v-2006-nissan-sentra--base--1-8l-l4-gas/body--roof-and-components)

If so, it may be possible that due to hardening, it may not be possible to stop the leaking. Funny though...I would recommend changing them out, but the part site I mention say they are discontinued (probably other sites carry it, if you do a search by part number.

P.S. Admins, please excuse my post of the link, and remove, if this violates the forum rules.

Thanks, Bob. I must have mixed it up with some other product.
@Eric, yes. That is the thing I am talking about. I asked the mechanic last year to replace it but he didn't think it was worth the cost and suggested me just to maintain it with 303 as long as it lasts. He probably knew that it has been discontinued but didn't mention it.

Slightly off topic now, but I searched the part number, and they are still available out there for around $60 (quick search only).
If you're anything like me (my daily "subway" car is a 2008 Yaris, just over 111,000 miles, and will hopefully keep going for much longer), I would want to stop any water from getting anywhere inside my vehicle.
My wife had a 1992 Wrangler, and its demise wasn't mechanical, it was rust (prior to me meeting her, the front drain tubes had clogged, causing water to accumulate under the mats in front, causing the "Flintstone Mobile" effect ;) ).

Thank you. I will have a word with him. This car is same as your subway car and same no. of miles. The water doesn't get 'inside' the vehicle but just the door seals which gets tricky in freezing winter when the door freezes shut. Otherwise, no problem.
'Flintstone Mobile' effect, excellent analogy, LOL.

It can be that the Sentra just have the kind of build so the water gets standing on the seals without running off. Then all the amount of 303 or Gummi Pflege won't help you sadly. You mentioned that the seals is exposed to the outside of the exterior against the roof.
When I clean extreme dirty seals I use a tire and rubber rejuvenate cleaner on the mf towel or spray it in a long bristle detailing brush. Hold the seal against one side first so I reach down to the bottom where you have the adisive against the vehical. Spray it on the brush or kind of in it from where it touches the vehical. And aggitate without pushing to hard and let the longer bristles work. You can if you have gotten like sand in those places also push at one side and vacuum out the most of the grit out before getting it wet with the cleaner. Dry it up with a damped with the rubber cleaner mf towel and follow with a dry mf towel. If you need to you can be doing a couple of cleaning with the brush to get it off. Let the cleaner dry as little as possible so the dirt not re-attach to it again. Work on small areas and stretch it out until the first part don't dries. It's no disaster if you follow up with the cleaner on mf towel it's useally okay. But it's extra work to let the cleaners dry.
This is just what I have seen on Youtube when they do the chemical torture testing with Super Clean. It leaves a lot of residue behind and you see how much harder it is to rinse off Super Clean than other products in these testings. So if you just wipe it off and don't follow up with damp or wet mf towel to soak up the residue. You have a lot of it left on the rubber. And it may have a big impact on the bonding of the product you apply over it. Some other APC is like this too and I don't like to use them for that part where it leaves a lot of residue behind.
It can be a longevity problem with the 303 Rubber Seal Protectant when it's exposed to the outside of the car like you have on yours. Maybe if you treat with the 303 Aerospace Protectant when the door is closed on the rubber seals. Then when it has dried open the door and treat the rest of the rubber seals with 303 Rubber Seal Protectant or the Gummi Pflege. Or if you get some other protection product that last long on rubber seals as recommendation. That you can use on the exterior part of the rubber seals. This is thinking out loud but wondering how something like Meguiars Hybrid Ceramic Wax should work on the rubber seals that's on the outside. Or any else of a high water repellent ability from it. Maybe even a tire coating or something like Gyeon Tire on the rubber.
I have had a couple of cars with this problem when they freezes shut whatever you do. So it can be just as the Sentra is.

This is what I’ve been using for several years and it works great. Apply liberally and then wipe off excess.
