HELP!!!! Boy do I have MESS

I bought Elmers Fiberglass Resin ( Lowes) and mixed per instructions, 14drops of hardner to 1oz of resin. Its been 4 days now and the stuff is SILL sticky. I tried another sample run and got the same results. It does NOT say epoxy but it does say it hardens ready to paint in about 2 hours.

Any body know what the problem could be??

Thanks,
Bill
