I have discovered extensive blistering , chips and cracking in what i imagine to be the gel coat on the base of my F2 xantos windsurfing board. I’m unsure how to proceed, whether to strip the coat (via sanding or scraping?) down to the fibreglass and reapply with a brush (any tips? never done this before) or ignore the blistering and just patch the parts where the coat has already flaked off.

I suggest that the gel coat was not properly catalyzed. Another possibility is that it was contaminated. You should talk with the board manufacturer or a ‘glassing’ expert. I would sand the gel coat off and lay on a new layer of gel coat. You can get such products from auto repair shops or chemical supply houses. Spend some time in the library and learn about fiberglass and resin construction. Humidity and temperature may affect your project. Read all of the instructions.
