I am ready to put the rear window back in my 70 Barracuda, what is a good sealer to use and where is it available.

3M makes the best stuff,I buy it in tubes for a caulking gun.I get it from a glass company I have a connection with,but I have seen it at my local Advance Auto parts store.

Thanks for the help is this the stuff you were writing about.
3M™ Window-Weld™ Super Fast Urethane, 08609, Black, 10.5 fl oz Cartridge

That's the stuff,I worked with a guy that installed auto glass for years.He swore that was the only thing to use.

It is very very hard to get out of the caulking gun manualy be prepared to have a soar hand. The glass guy I know has a battery powered caulking gun he uses. Whatever you do dont ever use any kind of rtv silicone sealant cause it is acidic and will cause you lots of problems later

We use a commercial grade caulking gun,not the stamped steel ones.They apply more pressure at the cartridge than other ones.
I agree on the silicone,the acidity will eat away at things.
