Good bye 90s doorknobs!! She took Rustoleum Oil Rubbed Bronze spray paint to the brass knobs in her house. We did ours about 4 years ago. most of them havent chipped at all. We did our light fixtures, shower trim, all doors, hinges, kitchen cabinet pulls and hinges, towel racks, Our pantry , door to the garage also. theyve held up REALLY well. If I remember correct we used a spray primer too.
