Steve,
Did you ever get around to trying this method? I looked around and couldn't find any M.E.K., but found a substitute at Home Depot called Industrial Maintenance Coating Thinner that is intended for "Use wherever MEK, Toluene, Xylene and VM&P Naptha are recommended". Well, needless to say it didn't do jack cr*p when I put it on my steering wheel. So unless I can find the real deal, I guess I'll have to settle for a dull/old looking steering wheel.
