Here are the only pics I could find of my hatch reseal project.
First two pics show frame temporarily re-installed to provide a solid way to scrape at the old glue with a razor blade and a sharpened scraper.
The third pic shows the glass being masked off after an extensive cleaning. The 08683 clear primer goes on next, followed by the black 08684 (both are water thin and come in tiny metal containers which you use very little of). The black primer leaves the black perimeter that you see peeling off of old hatches. After the frame and glass are cleaned and prepped, you reinstall the frame on the car then apply the 3M 08609 sealant to the recess in the frame. Next you carefully set the glass on the car and wipe off any excess that oozes out on the outside (if you put the right amount on, the excess on the inside will only ooze slightly out onto the black primer you previously applied which will appear basically like the factory applied job).
After curing, you remove the whole deal and reinstall the metal trim strips (after you cleaned then painted or powder coated of course!). Mine came out beautiful and thus far has held up perfect after 2 years of outdoor parking and use.
Here is a pic of daughter #1 returning from her driving test with a perfect score in the old non power steering, stick shift '77 924.
