[:@][:'(][:@][:'(] Been there done that! Sorry to hear of your travails. Man I glassed an entire plane once to not have the polyester resin kick off all the way and it stayed sticky. Turned out the hardner was old and lost alot of it's reaction. I had to go over it all again with a fresh batch and then sand my butt off with 60 grit paper. Then there's the time I mixed equal parts of resin + resin[:'(] Hang in there it will get better.
