Just thought I'd pass on a lesson I learnt last night. I'm very much a hobbiest and new to proper fiberglass. I'm no stranger to resin, though. The mixing ratio on the hardener bottle was a little ambiguous to me last night and I have some unset resin this morning. Instead of mixing 100 parts resin to 30 parts hardener  I thought the label indicated a range of 1:100 to 1:30 mixing ratio....
