[PSUBS-MAILIST] gel coat nightmare

[Rick Patton via Personal_Submersibles]

I hate working with glass and am not looking forward to making my MBT's!
if it's any consolation, I knew of a guy who was building his own 36'
sailboat out of fiberglass in the late 60,s and he didn't get the
resin/hardener ratio correct for the temperature and humidity for that day
and it never set up all the way! Never did hear what he did but probably
sold it as is where is and went out and bought one all ready done!
