Took me awhile to get the hang of it to but just do a small area at a time, dont do say the whole airbox cover at once. Small areas use the #2 until it`s dry meaning you dont see any more swirls when you go in a circular motion then use a clean cloth to rub it clean then after the whole piece is clean use the #1 polich/cleaner. I just had a epiphony I`m sure I spelled that wrong I am gonna make a Novus how to video lol damn I do have brain I think lol
