Then soaked a rag with WD40, and wrapped it around the blemish. Timed the soak by the time it took to open & enjoy 1 beer, then rubbed moderately briskly with the 0000 steel wool soaked in WD40. Success!!! No abrasion on the heat shields' chrome at all, in fact they shine like brand new. Note: larger or more persistent boot marks may require soak time of two or more beers. So, anyone want a can of MOCo boot heel remover.? No Thanks for all the replies and suggestions! Jeff
