Important!
Though some may have previous experience with polyester resins, we would like to highlight a major difference between the polyester resin and epoxy resins. Primarily, if you want the polyester resin to cure more quickly, it is perfectly acceptable to add more of the catalyst. This is not possible to do with the epoxy resin systems. Adding more than the correct measure of hardener will not make the epoxy cure quicker, it will only mess up the mixture and will result in the mixture not curing at all. Ever.
