The assembly line used auto caulking guns with Butyl, but this is a nice clean answer for one off's to install the back glass.
3/8" is the correct thickness for the Coronet / Bee.
No point reaching in and scratching quarter panel paint when you can just sit on the package tray to install the butyl!
Almost all the way around.
My lovely assistant of 36+ years. We took this car to the chapel and back!
Checking trim depth / fit before I get too carried away seating the glass into the butyl.
VERY light heat trying to soften up the butyl a tad so I can get it to come down a bit into the lower spots and seal.
Finally I just put the heat gun in the car and let it run until the car was up to 95F, then pushed the glass down. Still took a LOT of force, one arm hooked in the back window hole the other pushing down on the glass. No other way to get any leverage. Watch out for the hot brunette...
My last entry on back glass.. I promise!
. I wish it looked that perfect in person.
Don't forget your rubber spacer blocks so it doesn't slip down over time.
