It sounds as if you may have unusually brittle gel-coat and I wonder whether boats built at the same time as yours--with the same gel-coat batch-are having similar problems. For what its worth, Beneteau does sell Gel-Coat patch kits in matched colors although I do not know old the boats may be before the repair kits become unavailable. Another alternative is repair kit source is Spectrum Color
I have used the Spectrum kit and found it pretty good. Frankly, I also found that a thin mix of MarineTex, applied sparingly and "polished" with 600 and then 1000 grit works pretty well too.
I tried to find some info on the UV resistance of the white MarineTex, and didn't really. Do you think it has good lifetime with respect to UV? Or should it be painted over?
