Everything I'm finding says sets in twenty minutes to a half hour. I need time to apply the urethane, get the glass set in there, install a piece of rubber trim, then install the stainless trim all of which is held by the urethane. I'm doing this by myself, haven't ever done it before and therefore figure I'm going to be slow as hell. An hour or so of working time would be good and I wouldn't have a problem if it took overnight to set. Any ideas?
My glass guy is in the shop, cuts out a liftgate glass, and installs the new glass (or the same one in a different gate) in less than 45 minutes. But then he's a pro. That's why I call him.
There are a few that have slightly longer work times. I think Sika does one that's about 30 minutes and Kent about 40 minutes but long work times are not an attribute glass guys are looking for they want faster not slower. @Lloyd's paint & glass might have some suggestions.
Glass shops in the area won't touch it because it's an older car and not something they're familiar with. I had one shop insist that the glass was supposed to be rubber mounted. When I showed him the procedure from the factory shop manual, he said the manual was wrong.
My good old glass guy, he retired a few years ago. The guy was as good as gold. I'd suggest a shout-out to LLoyd at LLoyds Glass. I don't remember his @ right now.
