Recently, I bought a keyed glove box lock at a swap meet to add to my car. The lock was cheap, but a little discolored as the original finish had worn away, exposing the pot metal beneath.
While browsing the paint department at Lowe's the other day, I picked up a can of Rustoleum Bright Finish 7713 Dark Bronze. I have to say I'm extremely happy with the results. I did not spray the entire lock, instead just touched up the worn spots with the paint.
Let me know what you think.
