Nino,
I've just fired an email off to Jpop to see if he knows what the factory finish was.
The finish seems so thin (ie can rub through with a scotch brite pad very easily) I'd be surprised if it was plated, but you never know.
Worst case we should be able to source some 2k gold and clear coat it (again in 2k). Would not be a cheap option, however I would be reasonably confident it should stand up OK.
