Doesn't get much more unambiguous than that. 100 % Resin 30% Hardener
Ah, but that's because you're clearly not an "Idiot Like Me(tm)" BigGrin

Ironically, the gel coat hardener does put it in plain English: it literally says "Mix 5 parts epoxy gel coat to 1 part epoxy gel coat hardener". Even I can figure that one out.

Anyway, I've just laid up again, with 50g resin mixed with a further 15g hardener. Lets hope it sets now.

Hi Folks

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....

Funny that, because I got the mixing ratio on the Gel Coat just right.

EasyComposites, if you're reading this, may I appeal to you to make your labels a little more unambiguous for "Idiots Like Me(tm)"? Its really my fault, but maybe we can save someone else having to re-do about 10 hours worth of work.
