tteF aboB,
You're talking about a MSH, right? Mine came with a raw fiberglass finish, and don't want to put your head in that! It's ruff FG, and you need to seal it with either bondo or more fiberglass resin. I sealed mine with an extra coat of resin, about 2 oz. If your going to line your bucket with fabric anyway, you could skip it. But I'd do it just to be on the safe side.
