rear window installation ?

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

 

You can use the original butyl window seal. Get it from Autozone, 3/8", roll is about $15

urethane sealant here.

 

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.

 

i thought it was illegal to use butyl .

 

Not on cars that originally had it.

 

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.

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..

 

steve:
when i bought my shocks, ctc had a special, jan 2002, & i paid $29 each .

 

I'll have to see how much CTC funny money we have to get near that price!

 

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
