I have a 1976 Klamath 14ft Aluminum boat that I have questions regarding what I should do with the inside of it. It currently has three bench seats and the inside is painted camo. I'm in the process of sanding the outside to paint it a different color other than camo and didn't know what to use for the inside. I have used Rhino Liner in the past and I didn't get the results I wanted. Does anyone have recommendations?
