Autozone (or any other auto parts store for that matter) sells a scratch/chip repair kit by 3M. It's like $12-$15 and comes with the brush mentioned above, 3 types of fine grit sand paper, a little buffing pad that hooks to your cordless drill, a packet of paint cleaner and polish. It's a complete DIY kit, all you have to do is get the touch up paint. Someone keyed the side of my car pretty bad and I used this kit as a long shot fix. But it worked GREAT!!! the scratch is completely gone. After I saw what a great job it did on the side of my car I used it touch up the old rock chips on the hood of my car. I highly recommend this product. If you follow the directions and take your time you won't be disappointed!
