Friend built a Cheasapeake 17 in a class last fall. Had many helping hands and lost control. Now he has discovered uncured epoxy (not mixed or maybe even no hardener) under cured epoxy on small part of deck. The cured epoxy peeled off easily, now he has a gooey patch left. Sanding doesn't seem to be an option. Will laquer thinner disolve uncured epoxy after 6 months? I thought he could scrape until he's sick of it and try the thinner to get to something sandable.
Will the thinner damage the remaining sound epoxy? Thanks any thoughts.
