I just had my 1983 22 sisu bottom blasted. there are a lot of voids now showing on the hull. many of slightly larger than a pinhole, some about a quarter inch, and a some the size of a silver dollar. the deepest voids are about 3/8 of an inch deep. any recommendations for the best material to fill them with .i was looking at lbi 940 vinylester fairing compound.I am planning to do a barrier coat ,and then do new bottom paint afterward
