I am using tractor and implement paint with the hardener add to it. You can brush it on and it will dry with little brush strokes showing. Just light sand and put on another coat. I will put on three coats and sand to a smooth finish and then I will clear coat mine, but for a duck boat you do not need all that shine. Ace hardware has Valspar paint and the hardener. About 20.00 a gallon for paint and 25.00 for enough hardener for the gallon if you need a whole gallon. Good Luck!
