I am a newbie to i-boats.com. I just purchase a 1989 17 ft. Bayline Capri and i'm going to restore the flooring. I started this past weekend, and boy is it gonna be fun. I need some advise and expertise on what are the best materials do get the job done. Let's start with plywood. I know marine would be the best to use, but my budget will not allow it. I've check at Lowes and they carry both an exterior grade BX & treated. Would either work well if I was to cover the underside with and expoxy or a water sealer? What should I use to cover the topside. I've seen Bondo makes something called Bondo-Hair. It comes in qts & gallons. Should I use fiberglass mats & resins? I have had to take out all of the flotation from under the floor as well from under the seat bases. I've seen on a web site a 2 part mixture, but I've also seen at Lowes a 20# tank with spray nozzle that shoots a foam mixture like they insulate walls with. I can get this done, but I need all the help I can get and the best way to do it. If anyone has done a similar project like and has pics. Please send!!
