The reason I don't think that it is too heavy of a coat is this: The first light pass I had showed the "fish eyes" and adding more paint never improved them. As far as contamination this is what I did:
I wet sanded a previous water problem, cleaned with soap and water, cleaned heavily with metal prep, and finally went over the surface with a tack cloth.
Could too much hardener cause this? And would fish eye killer actually solve this problem. But if fish eye kiiller would solve it, what am I doing wrong in the first place?
