I’m building a motorhome on a Freightliner M2 chassis. I have the living quarters all framed out and I’m ready to skin it. Reading through 3m’s installation instructions for using the VHB tape has me a little nervous. It says not to attach the top or bottom so the panel can contract and expand without warping. Just would like some reassurance from someone else who has attached aluminum panels to their build with VHB tape. Did you take precautions so your panels didn’t warp? I’m using .050 aluminum and plan on using no rivets or screws just VHB tape to hold it on.
