Fiberglass Resin

I was helping my son do a little work on one of his projects last Sunday which called for some fiberglass work. He trusted me with the mixing (which I"ve done many times before) so I read the instructions for a change to be sure I mixed the resin right. I usually just squirt a dab of catalyst in the cup but wanted his project to go good, but I ended up MIS-reading the chart and put too little catalyst in the resin. Two days now and still gooey.

After giving myself a proper cursing, I"m searching for a way to salvage it short of stripping the mat all off and redoing it. Tried a little "hot batch" on top and it seems to be curing slowly, but still wet underneath. Any other ideas?
 
get some heat lamps on it, it should start to cure. i am assuming it is polyester resin. resin comes in waxed and unwaxed. wax is added to float to the top to aid drying. if another layer is added, the surface must be sanded to remove the wax layer.
 
I had that happen one time and used a heat gun to gently force dry it and it worked fine, sanded it and painted it. Then when the weather changed the stuff started lifting off so I had to chisel off the effected area and redo it. It was bondo brand resin and perhaps another brand would work different but I would recommend taking it off now.
