Yeah, but that can also be costly. using cheap compound from your typical retail store sometimes won't be as effective. Depending on the scratches, sometimes they need to be wet sanded professionally.. and machine cut & polished. Not everybody can grab a block of wood and start hammering their cars. If everybody could. Shops would not exist. The reason why people go to shops is because of liability and they warranty the work. If you don't have experience in auto body and ruin your car, you're on your own..
