My 1971 Formula is finally getting the paint and bodywork it deserves but my painter is conserned about the condition of the endura bumper. Whats the best alternative? All I've found is a fiberglass and carbon fiber shell. I'm not conserned about weight but I just don't like the idea of just having a fiberglass shell? Has anyone used the fiberglass bumper? Convince me it's the way to go! lol
