I'd appreciate suggestions or even links as I did a quick search but haven't found anything so far on doing something about the shiny silver surfaces that have been lost. Bought an old G1 prime and I didn't know the smokestacks, bumper and gas tanks have turned this dark blue color. Is there shiny type 'chrome' paint? My buddy said get some buffing compound but I'm pretty sure that's painted plastic on Prime. Beginning to clean the guy up now.... Thanks for any help.
