Side pipe sanding??

[Lowell W]

I think there was another thread on this topic within the last year. Basically, if it's a hard aluminum ceramic coating, you should (may) be able to remove the stain with steel wool and chrome polish without affecting the finish on the pipe, but try this on the underside of the pipe first to see whether it changes the appearance of the finish. If it's actually thick enough to feel as you run your finger over it, you may be able to chip or scrape it off with a sharp piece of hardwood. Pushing the car outside in the cold for awhile might make the stuff brittle enough to chip off easier.

Good luck, and please report back.
