Hi Joe, Correct me if I am wrong but isn't taking something abrasive like a scotch-brite pad something that is not recommended for the T-bars. It was my understanding that due any scratches would develop into fractures that will eventually lead the bars snapping. I'm game to try it as trying to mask off the area and paint them isn't my idea of fun, but I just wanted to put this question out there. I know that a Scotch-Brite pad is no where near as abrasive as sandpaper but is it soft enough to not damage the t-bar? The other question is, why would this area turn brown like rust? Thanks for the advise Tom #05732 DMC Joe Wrote: The "barber pole" strips on the door torsion bar are a stress patterns left by the "ten revolution twist in liquid nitrogen manufacturing process". The lines are easily removed with a scotch-brite pad. "We're here to help you"; See you in Cleveland! DMC Joe / De Lorean Services / <dmcjoe@xxxx> Web Site: <www.deloreanservices.com> .
