Is it OK to beach a fiberglass boat?
Sand (as in sandpaper) is abrasive. It will scratch gelcoat, possibly cause water intrusion into the fiberglass laminate, and remove antifouling coatings if your boat is painted. I know people do it all the time — I personally don’t advise it.
Is it bad to leave a fiberglass boat in the water?
A protected boat can theoretically sit on the water all year long, or even longer than that, but this is usually not encouraged due to the damage and deterioration that can occur over time. If your boat is already damaged, you may need to sand the hull, refinish it, and apply a protective coating.
Can you gelcoat over fiberglass?
Incorrect Surface Preparation – Gelcoat will only adhere to fiberglass, previously cured gelcoat, or polyester resin.
