Sticky wicket!!
This product arrived as described with one exception. There is a label on the front with a sheer plastic covering which mostly comes off, however the paper and adhesive remaining defy every solvent known to man!!! It has been soaked (twice) in Goo Gone, twice in rubbing alcohol, once in stainless steel cleaner and three times in Dawn power wash.....It remains.... I'd go after it with a razor blade, but I don't want to scratch the stainless.
