CV Boot / Weatherstrip Lubricant

[mopac]

Does anyone use the recommended GM weatherstrip lubricant (GM Part No. 3634770)?  If not what do you use for keeping the weatherstripping from drying out?

 

Should anything be put on the CV boots to keep that rubber from drying out?

Use dielectric grease.  That's actually what the GM product is anyway.  Smear it on heavy, let it sit for 30 min or so then wipe off the excess.

 

I've been doing this on my 2000 Camaro for, well, 19 years now.  The T tops don't leak or squeak.  I'd say it works.

Yes! I do this at least once a year!

I was asking about other's experience because if you look at the reviews on that Amazon link guys (mostly with Corvette t-tops) just swear by the uber pricey GM weatherstripping lubricant when compared to either silicone or dielectric grease mentioned already.    I mean the price is crazy for the small bottle.  But the reviewers just swear by it as the only thing that stopped their t-top seals from squeaking.

I don't recommend using it on the CV boots.  It will cause them to collect dirt and debris which may accelerate wear. It's probably best to just keep them clean.

Ohh man, I'll have to keep an eye out for that CRC...I like that "spot shot" dispenser rather than squeezing the tube like toothpaste.

Permatex also has it (both as a squeeze tube and a pressured bottle):

This is the bottle, dispenses by pressing nozzle sideways.

Yep, the old Cheez Whiz dispenser!  I have that permatex one at home.
