Now that my cabinet has been nicely re-veneered, the original gold metal grill on top needs attention. Since the bottom side show discoloration from the heat of the output tubes, I am assuming that I need to use a high temperature paint (grill paint, automobile engine paint, etc.). If I go with black, finding paint should not be a problem, but has anyone found a decent replacement for the original gold color? I don't want something that looks garish compared to the rest of the unit. Thanks for any suggestions,
