Reminder to self: NEVER buy another can of Rustoleum Painter's Touch Ultra Cover 2X primer!
I have had some problems with this primer but this tops them all. When finishing my Air Serpent, I used epoxy fillets and filled the fins with Fill'n'Finish. After sanding and wiping down, I shot on a coat of the aforementioned primer and left it for a couple of days. So far, so good. I filled a few defects with more Fill'n'Finsh and left the project for 2 or three days. Today, I shot on touch-up coat of primer and the stupid stuff crazed! It didn't craze on the Fill'n'Finish or epoxy before so am I to assume that it isn't compatible with itself? If I were a finish purist, I think my head would have exploded. Luckily, I don't care that much and will use up what I have.
