I have a circa 1965 Alcort Sunfish still sailing and in pretty good shape. But I'd like to make it as close to "like new" as I can; as I get ready to pass it on to the next generation. Unfortunately I loaned it to an in-law and it came back with a long but narrow gouge in the bow deck area. It looks bad but did not break through the deck in any area. I'm considering using the Six10 west system thickened epoxy adhesvive to fill the gouge. Is that the right material to use and will it allow it to be invisible after painting? Thanks a bunch.
