If it is clearcoat just get a can of paint stripper and it will come right off. If it is anodized and you will know when the paint stripper does not do a thing then you will have to get anodized stripper. I went to 10 diff. paint supply stores looking for anodized stripper and nobody had any, but you can order it off the web, just do a search for anodized stripper. If it is clearcoat, strip it then sand out the scratches with 200 grit wet sand then 400 then 600 all wet sand, it keeps the paper clean and surface area clean. then buff it out with wenol metal polish. If anodized and you can get the stripper it is the same process. If you cant get the stripper you will have to do what i did and sand the anodize off with 200 grit wet sand it will take a while though, then do the 400 then 600 then polish. It is alot of work but worth it.
