I'm helping a friend build his first SOF in my shop and when we got to the coaming, built up plywood, I normally glue the layers together as well as sticking it down and using it as a caulk using Lexel. I had an old unopened tube of the stuff which we used, came out thicker than usual and took forever, like a week, to set up, and some didn't set up at all. Also had a problem with it being incompatable to the latex paint we painted the boat with, peeled the paint off.

Again, worth testing ahead of time, which I didn't do, bad me. If you find a tube that's thick when opened, might be better to just discard it and find another tube.
