The bumper on my Bronze 99 is a metallic gray, anyone tried to match that, and do you remember what color you used?

 

consider going to a Sherwin Williams Automotive paint store or any other automotive paint store...you can get a single stage spray can mixed up for relatively cheap to the exact match. They have hundreds of swatches to choose from in the event your bumper is sun faded so the tint can match. Their swatch books are usually in 3 ring binders so you can take the page and match it up directly against your car in the sun for the perfect color match. Good luck!
