I read all the older posts this subject, however as "the times they are a changin'' what is the best product on the market today for cleaning, treating, and preserving all those hard (impossible) to replace rubber seals? My neighbor who has an auto detail business swears by Armor All 17451 Outlast Trim and Plastic Restorer.

As a rule we don't use anything Armor all. It leaves a film they is not good for plastic long term

I use dielectric grease for rubber seals. Very inexpensive and works well

I use Adams VRT for vinyl and tire shine for tires and running boards on my truck

We are scheduled to visit Adams near Boulder in May. In the past he has had great cash only sales and he does great demos

I go to my local Home Depot and in the plumbing department they sell silicone grease which I use on all my rubber trim I do it once in the spring and I'm good for the year .I have also used dielectric grease with good results as Rob said stay away from Armorall I quit using it for the same reason it leaves a greasy film and I think the stuff is overrated .

Hello,

Unless something has changed since the mid-1990s, Armor All is silicone with an emulsifier to thin it. They bought the silicone from Dow Corning (I used to work there as a student, and Dad retired from there after 35 years). It won't hurt anything, but there are probably better products. I used it on the door gaskets on my 1982 Chevrolet S-10 truck until I replaced them in 2007. They were worn/mashed flat but weren't deteriorating. Same with the interior plastics. It does make things greasy, so don't use it on steering wheels, or at least thoroughly wipe it clean afterwards.

I've tried a few products on interior plastics but haven't settled on anything.

I did try Nextzett Gummi Pflege Stift on the weather stripping. It comes in a small bottle with an applicator pad. I don't know if it's any better than anything else but it was easy enough to apply. The bottle looks a whole lot like the product Rusty Boltz suggested.

GM suggests DuPont Krytox for weather seals but it is not cheap by any means -- a quick check says that a 0.5 ounce tube on Amazon is around $30. I haven't tried it.

I also am using dielectric grease. When using it, I find the temperature should be in the very warm to hot range. The grease just seems to penetrate better that way. I let it sit out in the sun for a while before wiping off.

What about all the comments that dielectric grease collects sand, grit, dust, crud etc.?
Once it has penetrated into the seal or weatherstrip or whatever you have applied it to, you wipe off the bit that is still on the surface? :D

I've never used it so I'm guessing.

:dunno:
