I painted my brass plated bedroom handles over the summer, because I couldn't find new ones in the right size/color/price. Here's what I did: Soaked them in a mild vinegar/water solution. Rinsed them in clean water, then sanded them well to make sure the surface was scuffed up well to help the paint adhere. Next I sprayed them with an etching primer. Followed up with a oil rubbed bronze metallic spray paint. Paint and primer were Rustoleum brand. They seem to be holding up well so far. Don't skip the sanding, its tedious and not fun but I believe sanding is crucial to get a good adhesion. I didn't spray a clear coat over it, but I guess that might help. Let the paint cure however long is recommended before you attempt to screw them back in place and hopefully they won't chip.
