I scraped the front left bottom fender on a curb in my Honda Accord sport. How much $ to fix?

It's kind of a small scrape, but definitely noticeable. There's no dent but it's scratched.

Are you going to JUST DIE because your Accord is scratched? Take it as part of life. Dings and scratches. Keep 'em to a minimum, but don't lose sleep over 'em. A girl won't say "OH! His Accord has a scratch! I won't go to bed with him." and "OH OH! Gollygee! Oh oh oh!"

Why not go to a few body shops and get estimates for the repair.

$500 including repainting the whole bumper.

Just get a tube of touch-up paint for ~ $12 and take care of it yourself.

Use emery paper and touch-up paint instead of paying $500 for a body shop to refinish it.
