Fish eyes can come from several contaminant sources. Prep rags or towels, a contaminated tack wipe, or right out of the air. I tell folks to avoid running any internal combustion engine around a paint prep area. Diesel is the worst offender. The exhaust in the air can contaminate a surface.

Fish eye eliminator can be used in very small amounts to keep this to a minimum but it is basically pre-contaminating the paint so that it will lower the surface tension and adhere better. Just a half a cap full will work for a whole quart of mix.

Oils and any liquid forms of silicon or auto wax are the worst offenders to fish eye problems. Clean, clean, and clean it again using fresh cleaning materials.
