I do a wash with Meguiars gold class soap, claybar with mothers clay kit, polish with meguiars m205 (found online: autogeek.net) using a porter cable and white pad, then follow up with either meguiars tech wax paste (found anywhere) or blackfire wet diamond sealant (autogeek.net)

if you dont own a buffer/polisher like i do, you may still do it by hand. its just more work, and the results arent quite as good, but u should still be very pleased
