Hey guys what kind of selant should I use when I put my rear window back in should I use some sort of silicon or something else. thanks Adam
rear window gasket? So the butyl rear window gasket like you get at Autozone(for a 70GS) is 3/8" ? Flyin Buick, details on the urethane sealant?
Urethane was used on 78-up models. I don't use it because it is difficult to remove. You use a caulking gun to put it on and takes a lil more practice to get it right. Up to you which one you want/like.
then the exception has to be for windshields. i know that the car window replacemnet shops around here will NOT use butyl for any glass installation.
Be careful with the installer. Local shop made a real mess of mine, couple years back. First they sent a young inexperienced installer.I wished I was there! Both the bodyshop & I agreed to have someone else to do this. Applied a very wide strip of black primer on the back glass. Applied a very thick bead of the urethane on the window opening. When pressed together I ended up with a bit of a mess. The urethane is in contact with the corner pieces & sticks out in a few places. This stuff is just like tire rubber when cured. Front windshield was a bit worse. Too much urethane would not allow the chrome lower windshield trim to sit flat.Instead of putting the brakes on it I thought I could fix it myself. Started scraping the excess off with a razorblade/handle. Going pretty good until I slipped & sheared off the antenna cable. Had to replace the original glass with new. The green shade strip at the top had faded to a nice brown. The glass was excellent.
steve: i replaced the rear glass in my gs with a glass that i purchased from phil sedlon (on this site). mine was scratched very badly. i had a fellow at standard autoglass here in windsor do the replacement. i had dealt with him before with quarter glass chromes replacement & he did a fine job. i had no qualms with him doing the glass replacement. i actually watched the work being done.
I had the front windshield replaced by Apple Auto Glass, here in Saint John. Competitor to the shop that did the original install. I stayed to watch, did a beautiful job, even using the urethane. Rear window I'll deal with in a couple years. Keep thinking I can make something to nip away at the exposed urethane. Likely just have it removed, clean up the urethane from the sheetmetal & reinstall. Don't think I can save the plastic corners once I start the removal.
steve: i used krylon gray interior/exterior in a rattle can to paint the shocks. there is no paint code on the can.
Thanks Gerry. I checked with CTC & a local ACDelco dealer. They both have HD gas shocks available, $50.00 each Cdn..
the reason they want to use urethane is it has a better chance of sealing/staying sealed and these guys probably get paid more when they can beat the clock---it's easy to see which is faster. They also don't want any comebacks---less likely with urethanes I would bet. Liability obviously a concern also with newer cars/standards. If you have POR15 in your window channel applied over smooth metal then the urethane caulk will probably peel it right off as it dries. Patton
