Has anyone ever tried to polish the last few inches of a stainless steel tailpipe? I'm not talking about bringing the shine back to a factory polished tailpipe tip. I mean can you bring a plain stainless steel pipe up to a respectable shine with a few grades of sandpaper and some metal polish? My wife's 2006 BMW 325i has a short double tailpipe coming out of the muffler, and I'm wondering how shiny I could make it.
