Made a mistake this morning, I was going to paint some horticultural machinery with two pack car paint. Poured the paint and thinners in the gun, opened the hardener tin, and it had turned to jelly. So, either pour away the paint and clean the gun out “for nowt” or spray it on anyway and hope. I chose the latter, added a lot of extra thinners, and sprayed it on. Will it go off? If so when?
