Since it's just a bowfishing boat I might use a power sander.
Just a bowfishing boat? Isn't that the most important kind of boat?
I stipped my old boat inside and out with chemical stripper and some sanding. I left the outside bare alum and did the inside with bed liner. I asked a body shop about painting the alum and they said without the right kind of primer, self etching, the paint would not stick.
The durabak like my boat has is pretty easy to use and inexpensive.
