There's a couple of ways to strip paint. Chemical and sanding are the most common. Either takes about the same amount of time and work. Both make a pretty big mess. I did a 15' aluminum v bottom by wet hand sanding. Never again! If I were to do it again, I'd start with a chemical stripper, then wet sand it by hand. Everything is available from a hardware store. Since it's just a bowfishing boat I might use a power sander. You'll have to use a primer, but once again, since it's a bowfishing boat, you won't need to use an etching primer, just regular primer. I suppose if you didn't care how it looked you could do it hillbilly style with a roller! Spray cans would take forever and that paint is thinned down so much it doesn't hold up well. An air sprayer is the best method. It's all relatively easy, just requires some elbow grease!
