Oh Billy! I friend of mine just told me after the fact, that using spray window cleaner works great as a lubricant on the steel wool. Curious, I ran to my bumpers in search of an oxidation spot that I had missed, and there were several of the little buggers! Well, it did work great! ...and I didn't have to use as much pressure as I did using chrome polish as a lubricant. Darn... would have been nice to know before hand! Anyway, my newly buffed bumpers are smoothererer, slipperiererer, and shiniererer than they were before, so it turns out to be a blessing that the oxidation occurred in the first place! Hah! I'm never that lucky! 2016 is gunna be my year!
