I just bought a rear bumper for my car from a junk yard for like 25 dollars and it has a big blemish in the right side of it but the color matches well to my car. But i need to fix it and i was thinking about touchup paint.i am also looking to do some touch up on my car but i am un experienced with a paint gun so to cover large areas i was thinking of using the rattle can. But i was wondering how good is the match of the color? Has anyone ever used this site? To paint my rear bumper it would cost almost 60 dollars for just paint materials. 1 can of base coat, 1 bottle of clear coat and 1 can of primer. I just need your opinion and personal experience in this matter. www.paintscratch.com is the site.
