Help West Resin will not kick..

[nymack66]

I brought a Gallon of resin from West Marine it will not harden period whats wrong ? I mix a quart with 9 cc of hardener as instructed.
Never did the Resin brought from defunct Boater World failed me as a matter of fact it will always tend to kick early I miss that store .Not to mentioned I paid 1o bucks more per gallon ..
My only option is to wipe it clean with acetone and start over ?
