my back end bumper of my chevy cobalt is scratched? how much will it cost to repair?

[matt002004]

last winter i backed into a brick wall and scartched my bumper of my 2007 chevy cobalt. its not really noticable but i was wondering how much it would cost if i wanted to repair it.its about the size of a rectangle mayber 4 inches high 2 inches across
when i said repair i meant paint the surface

The entire bumper gonna guess $400 for paint and about 4 hrs of labor.
It will take a afternoon. Really rough est though

try rubbing compound it should move the paint around to fill in the scratch
