: Aesthetically, there is. If you're really concerned about the final
: appearance of your boat, let that epoxy cure a bit more, and sand the
: whole area off. Apply another piece of glass with thin (ungelled!) epoxy,
: and let it cure. Feather in the edges with a sanding block, and continue
: construction.

By the time you get this repair done, the epoxy in the unblemished areas (most of the boat) will be fully cured. It's been my experience that the fill coats should be applied before the wet-out coat is fully cured. Most epoxies need to be sanded once they have cured prior to another coat being applied - and you won't be able to sand the entire surface without cutting into the cloth. I would think it is better to do the fill coats prior to going back to fix this blemish.
