OK guys, no doubt it is suicide for a company to recommend abusing a product but I do know what the product will do, so be nice to me when you read this as it is my favorite example of how great this epoxy is.
A good friend who owns a Restro shop, i was visiting about 4-6 years ago and he was doing a 69 firebird for his brother, the rear window channel was shot after being sand blasted with baby holes all the way through. He asked if I would lead it for him, no thanks, to out of practice, so here is what we did.
Put duct tape on the back side and bend the duct tape up along the edge and shot epoxy, over an hour 5-6 coats, next day pulled the duct tape off, just perfect and smooth as can be, saw the car a few months later and like he said, this is the strongest piece on the whole car, glued in window and he has never had an issue with the channel, saved a lot of hand sanding and labor.
To this day, everytime he calls me, first thing he says to me, the rear glass fell out. LOL
Would I dare say, before anyone calls me a butcher, work smarter not harder. LOL
