My winter project is just about ready for flooring and walls. Im looking for opinions on how to attach the aluminum sheets to the trailer frame. I'd like to have minimal bolts or screw heads exposed on the floors and walls, and my first thought was some heavy duty 3M double sided mounting tape thats apparently waterproof. Anyone use this stuff before? https://a.co/d/c1U6Pwr

If not that my next thought was to use rivets. Anyone have other recommendations?
