I have an old wooden boat called a Bosarge. Well I was in it this weekend and when i put it in the lift I noticed an area where two peices of ply wood butt together. Well there is about a 3"x5" area where that ply butts together where a little bit of one layer of the ply peeled back. Just one layer which is no biggie, no waters gettin in. I can remove what has peeled, and any other loose wood along that joint. But what should I fill the area with? It is about 1/4" deep, on a vertical surface. I should have taken pics but I lost my memory card. Anyway I dont want to use filleting blend b/c I find it hard to fair and since this is a vertical surface i am afraid it would sag. Would that InterProtect Watertite stuff work? What do yall think. Thanks!!!!!!!!
