for Grandson's 64 stepside we're working on. Got some oak. Guess he will pick what degree of finish he wants and what stain he desires. I'll let him work up the blisters on that stuff. That'll show him the value of hard work while I weld in his new floor.
On my 70 LWB I bought some mahogany and milled it myself. A local company makes mahogany drift boats. I asked them what they use for a finish, they refered me to marine spar. They noted that no more than two coats work best because more than that can become brittle and crack. Mine looks beautiful with new SS strips.
