The hardware on my bass is painted black so that shouldn't be a problem. And it's not like I'm holding onto the tuners or bridge while I'm playing and sweating so I wouldn't really worry about the hardware that much even if it wasn't painted.
I've thought of coating the frets with something like nail polish but in my experience that never really helped with belt buckles or watches. It would always seem to chip off and then it's back to square one. I would only really trust it to not be a problem if is was nickel free to begin with. I could try it on my bass just to see if it helps as a temporary solution. But I feel the strings will probably just wear the polish off the frets and I don't know if I want to gunk up the frets and neck with layers of nail polish.
It's starting to look like all signs are pointing to a steel refret.
