ya, im surprised jon hasnt popped in yet.
mine took a long time to dry. i dont know if i put it on too thick or it was just cold. i ended up using an old heater on the outside of the door, set fairly low, about 35 hours, or more, after i applied it. that got the temp up enough for it to harden. however, i was told later not to use a heater. ken told me it could cause it to skin over and crack. mine didnt do that though. i guess the heat i used was low enough.
