View Full Version : 66 Mustang Windshield and Rear glass install

I am installing my glass in the car. All i have read says that you have to use a caulk style sealant.

I am curious, as this is a race/street car that will never see rain. Is the sealant keeping the window in? or it is just there for water tightness.

here is the only video i can find.

Water-tightness. From what I remember on my 66 Mustang, it was a heavy molded rubber gasket that fit all around the channel, and held it into place. At least it had to have been, because I installed it myself. But I didn't use any sealant, and never had issues. Never drove it in the rain though, but I doubt that would be a problem. Might have some wind noise, but it's an old hotrod... you should be driving with the windows down anyways!
