first get a jar a patience because you need plenty of that lol, to start you need to paint strip it with paint stripper remover then you need to wet and dry sand it (medium then working down to a fine paper 1200) using a dremil to get into all the hard spots, you need a bench grinder to polish with tight stitched wheel, medium stitched wheel and a loose stitched wheel.use black polishing soap with the tight wheel, green soap for medium and blue soap for loose. then use a pure silk piece of cloth ie piece of blouse ect then carefully rub with liquid diamond with silk. you a probably best of trying to polish your intercool pipes before rocker cover to get the hang of it. anymore help just ask
