New to the forums, but been following , on and off for some time. Anyways, I have some, way over the "opened" shelf life, epoxy activator left. I also have some gray primer, old as well, thats been stored in my basement cabinet. So the other day I pulled them out and stirred the primer, and mixed with the "aged" activator, ( just about 6 oz total) ,and using a foam brush, spread some over a inner part of a 67 Chevelle fender, and a steel 1" plate.. as a test. They are both totally dry, and appear like a day old primer! . SO , why not use the stuff?? I am thinking on using it on, non painted surfaces of my Chevelle (floorboards, inside trunk areas, etc). If its hardened, whats to worry about? Im totally stunned that it dried, to be honest.
I airbrushed some bike parts in the past, and found out the hard way about the life of "opened hardeners" in my clear. The clear on that tank felt rubbery, and left fingernail imprints in it. And so I had to strip it all off, artwork included. I expected the same to happen here, with the epoxy. and am surprised that maybe I can still use whats left. As you know, nothings cheap these days.
