I had the exact same problem when using the Rustoleum for my kitchen handles. The paint didn't adhere after using the handles for about two weeks. I became frustrated and bought some automobile spray paint!! I followed the directions exactly and now, after two months, the paint looks as good as the day I painted. I used a matte silver. According to the men working at the store they said auto paint is better (after all, your car gets hit with rain, hail, snow etc.) You can buy almost any colour and finish (think of the new car colours) and the price is amazing.
