This stuff might be the best in the world, but 7 DAY CURE TIME?  Stupid me for not checking the specs more closely.  This sealant is recommended all over the place so I just ordered it without even thinking a company would make a marine sealant that took a week to cure.  We've had 80+ weather for 5 days now and my boat is stuck on the trailer waiting for this stuff to cure.  It better hold for years since it ruined my weekend.
