sand it down with fine sandpaper, than use a solvent to remove grease and oil, than prime it, than sand again, than paint it, than clearcoat it! lots of work! if you want it professionally done! I can do it for you if you live in vancouver, since I work at a body shop here. your paint is special I think u have the "desert silver" I can paint it for your if you like color matched at your cost, or you can do it yourself the paint number is usually on the door jam...
