I don`t know what material was used to achieve the "insert"
but I`ve had a very difficult time removing it from my two project emblems. I`m open to any suggestions on how to remove the old plastic/resin without damaging the underlying chrome.
..beyond sheer mechanical methods, (which I'm sure are not the way to go!)... heat, and/or chemical... Kinda curious what manner of compound(s) were in japanese automotive use in the early '70's...? Regardless, you likely know much more than I about the limits of solvent, etc., use without affecting the chrome... What are the odds it could be softened up enough to remove without damage? Same thought on the cautious application of heat...
Or, 'WWCD': What would the chromer do? How does the current state-of-the-art in restoration deal with prepping such a piece for re-chrome?
