Fisheyes generally come from oil or silicone under the top coat. Back when I was teaching auto body classes in a big high school we started getting a BUNCH of fisheyes in paint jobs. When we finally found the problem, it was caused by one of the students using large quantities of Vaseline Intensive Care lotion to treat a dry skin problem, and rubbing his hands over the body work to check for surface smoothness while he was sanding Bondo and primer. The fisheyes were coming up like popcorn!
