IMG 1673 Leftover Interlux e2000 epoxy sealer from the outer hull job makes a great primer for Bilgekote or it can be left alone if kept out of UV (like down in the bilge). And it adds waterproofing to your new fiberglass work. Definitely roll or brush some clearcoats of West System over the fiberglass to obtain smoothness before the e2000. You don't want crevices that will retain dirt and look bad over time. I added G-10 blocks on those four keelboats because I needed more flat surface for the stainless washers to clear the bilge sides.
