I cut the trash down with 1500 (wet by hand), then cut orange peel with 2000, (wet /by hand)then hit it with abralon or trizac 3000 or 4000. Then Polish with 3m's 3 step system of compound, (wool pad) finesse (foam pad) and ultafina by hand with microfiber towel. Barry I think recommends presta products. Cut it and let it set a day in the sun or two days inside it will be amazing how nice it buffs after the surface is broken and it is allowed to gas out. I use spi clear exclusively and cant say enough about how nice it is to work with.
