Remodel dilemma: Paint or replace doorknobs?

Homeowner wants knobs to match bronzed bathroom fixtures

Q: To get the particular look I want in my home, I have used Rustoleum to paint the brass on the fireplace. I also used copper and black to give the bathroom light fixtures and towel racks a bronze look. Can you explain how to paint the door levers since they will be touched daily? Can the bathroom faucets be painted from "gold" look to "bronze" look? Any suggestions would be greatly appreciated. –Della W.
