I don't know if this is a problem or not.
I have a fender in black SPI epoxy primer that was primed in August when it was around 84 degrees. It sat in the sun for 2 days and has had no bodywork done to it. I wanted to check the epoxy adhesion so I sanded a spot with 80 grit (on a block) down to bare metal. The epoxy feathered nicely with a smooth edge. I put a razor blade scraper to it and to my surprise the epoxy just peeled right off, cleanly, leaving nothing behind.
I expected it to put up more of a fight.
Does this sound like a possible adhesion problem or is it normal?
