Gelcoat does wonders to repair a mistake,just gotta make sure the repair behind it will last and not come back to haunt ya. Just sayin.

Gelcoat is a no-no over Epoxy...
Grinnd out the bubbles feather the edges with thickened epoxy. Let dry, sand whipe with acetone. Remember, with West System, once you miss the recoat window you will have to lighlty abrade and whipe with warm water or acetone before you apply any subsequent layers of glass/resin.
West System has a rather high amount of Amines in it which come to the surface once fully cured. Without removing any amines you will not get the good bond between layers/coats.

With all that said, it shouldnt be that bad. 36 grit sand wheel on a buffer you should be able to knock that out in no time...

What temps are you working in? you using the fast catalyst or slow? That will have a lot to do with fluid penetration. Are you using a resin roller? Squeege?

Just some things to digest...
