This seems like the way forward and a cost and effort I’m willing to take on, but I’m trying to decide on the best epoxy for the job. I have had a few people recommend the gel coat can be skim coated with an epoxy resin (after a thorough clean and keying in parts) to form a new smooth base (possibly after some sanding) on to which a paint coat can be applied. The extent of crazing makes it impossible to feasibly open all the cracks and fill while the boat value doesn’t make gel coat stripping viable at all.

Any painting over the gel coat as is would likely just show through the crazing in time.

This isnt structural stress related, but is rather fairly uniform across the decks and coachroof seemingly from uv deg or possibly the gel coat being laid up a bit thick back in the 80s. Most problematically there is a lot of fine crazing. I have a reasonably decent size GRP sailing yacht, which is quite old, and the gel coat is suffering a lot in discolouration. Hi, Very new here - so go easy on me but help appreciated if possible.
