I used this tie coat primer over a sanded and prepped fiberglass canoe hull. It worked well under an automotive-paint finish (above water line) and gave surprisingly good results under Pettit Vivid anti-fouling bottom paint (below water line. Overkill for an old fiberglass canoe? Perhaps, but I was practicing for replacing the bottom paint on my 1984 sailboat.

Applied very easily by brush. Coverage was right on the mark from the specs on the can.
