Re: Valiant 32 problem with Fire Retardant in resin.
You will hear a lot of different opinions about blisters in fiberglass boats. Lots has been written about it on the internet, including this site. IMO there are some cases of blisters in the hull that can lead to potentially serious structural problems, but most blisters in the hull are just a cosmetic issue or surface roughness that leads to minimal loss of speed. Blisters in the deck and cabin superstructure are different, as they are above water level, so if a leak was to develop, you would detect it quickly, same with any potential structural weakness (you are walking on it all the time).
Fixing is quite simple: dry, sand, fill in with thickened epoxy, sand down, paint. No great mystery here and also much has been written about it on the net.
Be kind, for everyone you meet is fighting a hard battle.
