So last weekend my spray paint /debrass project was the kitchen knobs.
This is what they looked like before....
(can you tell that the oven is circa 1991 as well)
First I removed all of the knobs and washed them with soap and water.
After they were dry I used a medium grade sand paper and I scuffed up each knob. From what I have read this provides a rough surface and the paint will adhere better.
