I used 2 quarts the first time on a clean litely sanded (scuffed) bottom. I put a space heater under the boat the first time and it started setting up too fast and was tough to work with.
the last time I used the heater after to help it dry faster. I would give it 36 hours with a heater for the first few hours.

when the hardener is added work fast while it's easier to work with. Good luck!!! and get that thing in the water
