Jim,
Could you tell me if the stainless steel full body length side trim, and the fine line brushed aluminum insert trim on a Jetfire can be straightened and polished. I figured your the guy to ask since your “jetfire” convertible looks great. I am looking at purchasing a set and in the event there are kinks and bends, I wanted to be sure they can be straightened and polished.
Thanks.
Charles
