i gutted a lp copy recently but couldnt get the bridge studs out. They're nickle and im switching all the hardware to gold. Does anyone have experience painting guitar hardware?

I was thinking some model paint and a real small paint brush?
i already painted around them :/ Wouldn't want to risk cracking the new paint on the guitar.

If there's no effective way to paint them, i might just go with nickel hardware again... : (
