i had a very similar scratch on my front bumper... what i did was i went to autozone and got some oxford white spraypaint and clearcoat. I cleaned it as hard as i could so that i knew only the part where the paint was taken off was left. I then used masking tape and taped all around the scratch being very detailed leaving only the scratch exposed. Then i taped up some newspapers covering almost the whole front of the car, just to be safe

. I then put like 4 coats of the white spraypaint on and, after everything was good and dry, i put like 3 coats of clear. Probly should have done more coats but i was out of dailight and i needed to drive the car the next day, and i didn't want to do all the detailing with the newspaper and masking tape again. I will warn you that my paint color did not match perfectly, put it looks better than it did...it was hardly noticeable to begin with... Good Luck
