How do you fix fish eyes on epoxy?
by
Lightly sand the existing epoxy with 120-150 grit. Care should be taken not to cut through the stain. Apply another seal coat of epoxy using an 1/8″ nap foam roller, working to fill in the craters. Allow the epoxy to cure hard, sand entire application flat, and re-coat to finish.
Substrate contamination is the most common problem that causes fish eyes and pinholes in epoxy seal coats. Dust, dirt, wax, silicones, even the oil from your fingers when touching the part prior to sealing with epoxy will deter epoxy resins from laying flat and curing with a perfectly smooth surface.

How do you smooth bumpy epoxy?
An uneven hardening of your epoxy resin can lead to dull, or even tacky spots. To fix an uneven epoxy finish, wait until the epoxy has dried thoroughly, and then sand it lightly with fine-grained wet sandpaper. After this, make sure to wipe down the surface, so it is entirely free of any sanding dust and other debris.
Use masking tape to cover the hole as soon as it is filled. This will prevent epoxy draining out before it cures. Cover the hole with masking tape before you inject the epoxy. Puncture a hole in the tape big enough for a syringe and inject through the tape into the hole.

Pinholes can only be repaired successfully by thoroughly sanding the substrate or by filling the holes with body filler.
