Aaaaaaack!! That will ruin the collector value, Reading this thread almost makes me wish I has stuck with the Trac II and canned gel. Almost.
Ever considered how nice a Trac II handle would look in a bronze and gold camouflage pattern cerakote?
In my humble opinion, based on extensive observation, plating or cerakoting almost any razor will increase the value. First and foremost people cerakote or re-plate a razor for their personal benefit. The value of almost all vintage razors will increase with new plating. There are only a few very rare razors that would suffer if the original plating is altered. One modifier to that last statement is if the original plating is in horrendous condition. Any razor, including extremely rare collector's pieces, with extensive plating loss or damage will, also increase in value provided the replacement plating is true to original. The bottom line is there are more people that will pay more for a newly re-plated or cerakoted vintage razor than there are those who will pay high dollar for a razor in original condition. Personally, I've been wanting one of the Delta Echo razors in a bad way for a long time.
