UH oh!!! resin help!!!

[Kracker Jack]

Layed a piece of 18 ounce on the inside of my outer skin today at 4:00 pm. Mixed resin and hardener as specified 1 tsp. for 1 quart in 70 degree temp(I put 5 more drops in because it was 62 degrees outside). It is now 6:50 annd the temp is dropping and the resin I applied to the 18 ounce is still wet to the touch but the pot i mixed in with minimum amout of resin is gelled up. will the resin i applied to my nnew skin set up with the temp dropping?
