IF you have not mixed the hardener to it, it will not cure. If you have mixed the hardener to it the resin will cure. It cannot be stopped.

RE: Fiberglass storage?
to rephrase , When i store fiberglass resin which is not had any hardener added it seems to last a short period of time before it crystallizes in the can. Is there a method of storing the resin which slows down that process. Would putting it in the fridge help? Similar to CA glue.

I am guessing this is Polyester resin. There are many "Variations" of polyester resin it is difficult to knwo what you have. In many cases the quality is not the greatest. Some of them even have additives to lengthen the shelf life. The polyester resins available in hardware and automotive stores are of dubious quality. Purchase composite materials from a composite supply store.
Polyester resin should not be allowed in a domestic environment. The hardener is extremely dangerous. The tiniest drop in the eye WILL destroy thet eye. IT CANNOT BE WASHED OUT QUICK ENOUGH!!

Hi, All polyester resins have an additive "cobolt" in it. This is preadded during the manufacturing stage but the greater the amount then the shorter its shelf life. The other side of the coin is those resins with more cobolt will also cure more rapidly
