The Stovebolt Site Forums The Shop Area Paint and Body Shop 3M 8509 glazing and bedding compound use...

I may have made an error in using this product for sealing around the windshield and rear window on my 55-1st Series. It's now been about a week, and this stuff is still tacky when you press on it. It states on the tube that it remain "soft and pliable", and I thought that meant it would cure similar to a rubber like product. Has anyone used this stuff before, and a)does it ever cure up, and b)is there a better product to use (sealing between the metal, and the rubber gasket. I hate to think about digging all this gunk out-spent quite a while getting it nice and neat. It does look pretty good! But like that tease back in high school-look but don't touch!

It sounds like a similar product I use called Arbomast.
If you have used it correctly you shouldn't be able to see it,yet alone touch it.
Did you remove the lock strip on the rear rubber?
You should pump the sealer between the glass and seal and also the body and seal. When you install the lock strip the excess will ooze out to be cleaned off in the manner I describe below.
For the front rubber do the same.
Although there will be no lock strip.
Simply wet it down with glass cleaner or water and remove the excess with a plastic scraper such as a bondo applicator.
That way you wont 'hurt' your paint finish.
You can clean off any smearing with white spirit/turpentine or paint shop panel de-greaser.
I hope this helps.
