I would start with cleaning the surface to see what scratches actually exist.
You could get some normal paint thinner and apply it to a rag and then wipe the surface. Dont worry, the paint thinner will evaporate and not damage the rest of the finish. Once you evaluate the scratches, get some touch up paint from your local bodyshop or dealer and a fine brush. Touch up the scratches and see if you are ok with the results. If not, then it is time to get an estimate.

You wont be able to duplicate a base coat clear coat finish with anything at home or from Home Depot. If you just need some minor repairs and refinishing, you will be in the 5 to 700 range for repairs. A good collision center will be able to repair the cover without problem.

Best of luck!
