I applied some coating resin to a part about 2 weeks ago.  and even now it is still slighlty tacky to the touch.  Weirdly the excess resin in the mixing pot seems to have cured fully and is not tacky.  I used a digital scale and am pritty sure I mixed it 2:1.  The part is made from glass cloth and EL1 laminating resin.
Any idea what could be the cause of the tackyness, and any way I could salvage the part?  It took me quite some time to make the part so I'd really hate to have to toss it.

what temperature are you curing that part? must be over 15C° at least!
