          I used 404 High Density filler while rebuilding my transom. It sets up extremely hard. Very easy to work with and mixes well.

            In the process of restoring a 1976 Venture 25 I have found 404 High Density Filler invaluable. I have used this filler mixed with 105/205 West System epoxy with amazing results.
