The finish of your new Van Dusen racing shell is either two part polyurethane or epoxy gelcoat. It was sprayed into the mold before we constructed your boat. It is bonded into the outer layer of fiberglass during the heat and pressure curing process in our autoclave and is extremely durable. Minor scratches can be repaired with standard automotive polishing compound. Major scratches, usually the result of surprise meetings with a log, rock or dock, may require filling to retain a perfect hull finish.
