Actually regular 5200 takes (according to to 3M website) 5-7 days to cure, 48hrs to become tack free. .
They do make a fast cure 5200 and 4200 though and. Fast cure is tack free in 1 hour and cures in 24. Boat life may be good too. On fiberglass, 5200 can be a bear to get off. Some people have 5200'd their engines to the transom (for sealing) and have big problems getting the engine off. My friend had a guy bring him a boat and told him he couldn't get the engine off. My bud said the guy had towed the boat from his house to the shop with no bolts holding the engine-just 5200!! He said it took a while to get that engine off!!
We'll see I guess.
