BufordT:
I used the FRP for my inside ceiling and lined the inside of my hatch with the stuff. First time I every used it and was impressed. Wanted to use it
as an outside side skin, but my daughter likes the look of aluminum.
After working with aluminum, seems the stuff scratches just by looking at it, wished I would have more seriously considered FRP, painted to match the tow vehicle. May have used roofing rubber for the top.
