Ok, I must have done something wrong. I had to sand all of the blue paint off this morning. I waited 24 hours and tried to wet sand before the second coat and it was just peeling off in spots and gummy in others where there was SEM self etching primer. On the flip side it was dry and hard on the other half of the decklid. I am thinking either I did not clean the surface as good as I should have or I did not wait long enough. So I just resurfaced the decklid and laid down more etching primer as I cut back down to the metal in spots. Do you think the rustoleum is not compatible with SEM etching primer? They sell a marine primer I am going to try if it does it again. Your thoughts??
