I'm no expert on GRP but I know it is possible to paint on gel
coat after you have cleaned up the surface.? You won't get as good
a finish as a boat out of the mold, but it will be better than the
flaking you currently have.? I would try in one area first, remove
us much of the flaking and sand to get the best surface you can,
then paint on one or more layers of gel coat.? Matching the colour
so the transition fro new to old won't be easy.
Good luck

The hull of W537 is in really good condition if you look at the
outside.? Inside, however, has areas where it looks like the
gelcoat is flaking off.? It seems to me that this is cosmetic but
I am not sure.? See the photo below:

I was planning to use a pressure washer to clean up the inside and
remove as much of the flaking stuff as possible.? My question is,
how much should I remove and what should I replace it with?
Thanks!
