I'm looking for a material to make a bikini top for my CJ7. It will mount to the 6 pt cage. I'm moving to Hawaii so a hard bikini top should be perfect and help strengthen the cage and protect my head. From some other posts I looked into UHMW polyethylene which I think will work well. I don't want much weight up that high and aluminum will corrode. The interstateplastics website says that the UHMW isn't UV stabilized. Will this really make a difference? Also how thick a sheet would I need? I'd think 1/4" would be plenty. Any info would be great.
