There's been a million threads on what to lube/protect the weatherstripping with. People have recommended everything from pig snot to used motor oil (just kidding).

I've got a simpler question:
My 2009 manual recommends GM Weatherstrip Lube #3634770, how does it work?
Is it waxy, or greasy, or just slippery like silicone spray?

I've used the Diaelectric Silicone Grease for many years, it works well but it's rather messy and also attracts grit. It does seem to be effective; we applied it to our 2001 once per year, never any squeeks and the rubber looked like new when we traded at 6 yrs/68k miles. But if I can get the same results with less mess, that would be nice.

GM Weatherstrip lube or Superlube is effectively, Dielectric Silicone lube. Your experience using the GM product or it's non-GM counterparts should prove very similar to your past results with Silicone lube. Any O-ring or gasket lube should take care of business.

As you said there have been many threads on this...

I used the GM recommended stuff and didn't notice any different between their super expensive grease and cheap dielecric grease. Both worked the same and both were greasy and left streaks on the window even if you wiped most of the junk off...

BTW, you should never use the spray stuff unless you are sure it has no pertoleum distallates (spelling), otherwise it will crack you weatherstripping in the long run...

Here is something funny though: my second car is a BMW Z4, in their owners manual it actually states to not use anything on the rubber, just to keep it clean, it goes on to state that using lubricants and or grease can damage the weatherstripping. I never could figure out what the difference between BMW and GM weatherstripping is, but they recommend different ways to maintain it... Go figure...

I use dielectric grease twice a year. Rub it in, then take a dry rag and make a pass over it to pick up any "extra". I dont notice a collection of debris attracted by the dielectric grease.

I have a friend who has been around cars for a long time and he told me to use vaseline. Put it on let it set for a bit and wipe off extra with a rag. So far it seems to be doing a good job.

I used ARMORALL on my other vehicles watherstripping for many years, is this no longer a recommended product?

I have and use GM #3634770 weather strip lube. It comes in a 1 ounce bottle. A little bit goes a long way w/ this stuff. It has the consistancy
of shampoo.

It is $$ to buy, so I only use on Vette, On Silverado, I use dialectric silicone grease....both seem to work great.

This is an excellent lubricant.

I would recommend staying away from using the SuperLube on the weatherstripping. I used it on the weatherstripping on one door of my TB SS to see how it worked. It actually makes quite a mess. It dries out and turns a somewhat chalky white. Not what I expected at all.

If anyone has a tube of the GM Weatherstripping Lube, could you look on the back of the tube to see who actually makes it. The actual manufacturer of the GM branded stuff generally sells it under their brand name for less than half the GM cost.

Armorall is like putting bleach on a new blue shirt!!

Use 303 Aerospace Protectant

I use the Shin-Etsu Grease. This is the best stuff to use IMO.

...easy to apply, and no mess if you wipe down the weather stripping ~1 hour after applying. This gives the weatherstripping plenty of time to absorb what it needs, but removes any excess. It really makes a difference.

I use Krytox a small tube is $45 and really is a great product. I got it at MidAmerica/Ecklers. I hate doing this every year with the cheap stuff the Krytox while extremly expensive last a couple of years. The tube will last for about 5 to 6 complete uses.

From what I've read, GM #3634770 appears to be DuPont Krytox GPL 105 oil.

Interesting DuPont links:

Mine is in a tube yours looks easier to apply what is the cost?

I just purchased a tube of Dielectic Silicone Grease GM part #12345579 to treat all the weatherstriping on my C6.

Upon reading the directions it indicates that this product is "designed to coat the inside of spark plug boots to prevent them from sticking to ceramic insulators".

Can it still be used to treat weatherstriping?

You actually don't need to use anything other than soap and water and putting petroleum products on can break down the 'rubber'.
