Repairing cracking gelcoat
Hi everyone. I'm new to this forum and it sure looks like this is the PLACE to get boat repair information.
I have recently purchased a 1963 GRP Silhouette sailboat. I am going to try and completely restore the boat. I have begun to sand off the old finish, so far I have got the hull sides from the deck down to the waterline and the transom sanded. I used a random orbital sander and 40 and 80 grit.
What I have found so far is that the surface is cracked and crazed fairly extensively.I would say that the
gelcoat is essentially gone. Would it be better to;
1. Use a fairing putty to fill and smooth the surface then use a high build
primer and paint? I have heard Pettit makes a good one.
2. Coat with epoxy? West system or other.
3. Put a layer of say 1.5 oz. fiberglass cloth and resin? Polyester or epoxy?
