I scraped the front edge of one of my rear fenders on a brick wall recently, trying to maneuver in a tightly packed garage. Entirely my fault. It's an eyesore and the scratches definitely got through the paint, but not quite to the metal.

I just want to touch up the blemishes for now so they don't look too hideous. I figure a paint correction is in this car's future at some point anyway as most of my miles are highway and there's a fair bit of debris around.

I was told by a Mazda dealership that they only sell touch-up pens, which are only for tiny and thin scratches. Any thoughts on something better?

 

Pics? sounds to me like the damage is beyond a touch up. You can get factory color match spray paint. Google

 

It definitely is beyond a touch-up. I'm not trying to make it look like it used to. I just want to reduce the hideousness.

 

I've used Dr. Color Chip for deep scuffing like that. Ymmv, but when done carefully, it blends very well.

 

^ +1 , used DCC myself, the color match was spot on for my SBM

 

I have gotten spray cans of Mazda Winning Blue from the site below. Color was spot on. Give them a shot.

+1 for Automotive Touchup. I've rattlecanned my eyelids and re did my cheap poly front lip with their paint and color was spot on. I'm sure their touch up brushes would be an accurate match as well.
