Yes, the gold plating has worn a bit thin on the main body of the tuners but not elsewhere.
They did look great when I first did them, but they are on a 1973 Fender Precision which I want to restore to its former glory.
I might try and buff it off as suggested, however I think I might have to have them re-chromed, whether this can be done on top of gold plating I don't know.
