I would put a disclaimer on them motorhead,Some idiot is going to put these on a steel bumper and create a problem,Just put a little sticker saying "For fiberglass bumpers only"
I considered having "for off road use only" etched on the large parts. Most likely when the website is set up with a purchase route, I will ad a disclaimer. Im not a attorney so I do not know if that will do. Im just a millwright trying to make some light weight parts for our race cars! lol.
