Hi, Ian:
I had the same experience where the glass seems to have mounded up over excess epoxy. Fortunately this happened inside along the keel, and is not easily seen.
I left mine, but I suppose you could grind them down flush. That'll leave a hole in the glass unless you add a patch. That may show, too. MAybe someones got a better idea! Very best! Rick........
