I'll add my two cents on epoxy fisheyes... in addition to what the others have mentioned as possibilities. In my experience with rattle can products, including Krylon and Rustoleum, there is something in the carrier that needs time to "cure" or evaporate completely. I don't mean skin-over or feel tack-free... I mean cure. If you can still smell the paint, it's not cured.
I know, I know... sometimes it's not a problem. But summertime humidity slows that process dramatically.
Secondly, sometimes "we" play with the epoxy too much while brushing on... stroking back-n-forth, back-n-forth, trying to get that perfect coating. Epoxy doesn't need all that care. It's self-leveling in most instances, but won't flow where you don't put it, and won't stay where you don't put enough of it... the epoxy film looses surface tension and pulls back, causing the fisheye craters. Just make certain you're applying a uniform coat, stick it on your spinner, and check it after 15-20 minutes to make certain it's not bubbling (inadequate sealing) or fisheying. You can still fix it at this point -- depending on the brand -- with a toothpick dipped in leftover epoxy and dabbed on the spot.
Worst case, if it does fisheye, just let it dry tack-free (8 hours or so), and then just recoat. Nine times out of ten, the extra 0.1 ounce of epoxy won't harm the plugs action, and the fisheyes will magically disappear.
