Depending on the depth, you may not be able to get them out. If they are light surface scratches, color sand with 1000 grit, then 1500 grit, and buff with compound followed by a step 2 compound and finally carnuba wax. If the scratches are to the primer or just too deep to sand out, you can apply touch up paint to the scratches and let cure. After curing, repeat the above color sanding steps.
