Re: Spider Cracking opinions wanted
I've had spider cracking on two boats, including the one I have now. As mentioned above, it's just the gel coat. As far as permanently getting rid of it, forget it unless you want to grind off all the old gel coat. The best solution is to consider it a maintenance issue which will spur you on to repaint every ten years:-) If you clean with a good solvent, squeegee some epoxy in, overcoat with a high-build primer and then give it a nice Awlgrip finish, it will last 10 years, showing the first sign of the cracks reappearing after 5 yrs or so but they WILL reappear. I've never heard of any other options other than to grind it off, lay another complete layer of fine cloth over it, or cover it temporarily.
+1 On BarryL's comment on core rot. That can be a major problem.
