I want to start my FG project tomorrow and I need to know how much MEKP to use. I got a tiny bottle with a whole gallon of resin. Is that enough to harden the whole thing or do I need more? With epoxy resin the ratio for med to hot is like 3-1 or 5-1, why do I have so little MEKP to the polyester type?

Thanks

You only need 2% or less by weight of MEKP to catalyze polyester resin.
