Hey Heath, If you want the car to really shine, then you need to have good surface prep. I'm not sure what your process is, but have you dawned and clayed the car before? You should also include an abrasive like #9 to elimate some swirls and scratches. You could also look into #82 Swirl Free Polish (to use after #9 or in place of it), I was really happy with the results on my true blue, it'd look even better on black. I've never used #3 before, but the reason it is probably so difficult to come off is because your orbital cannot generate enough heat to break down the substance all the way. I'd use #7 or #81, like Bob said. Then naturally follow with 20 or 26. I personally hate to cross brands, so I wouldn't use the Mothers. On a side note, I currently have Zaino on my car. The products are definitely quality, but it just doesn't give me a Meguiars soft/deep shine. It is more hard and glassy looking. It seems to do better against the elements than my Meguiars did, and as I near crappy weather in Washington I need all the durability I can get.
