I've used a ton of Presta over the last 10 years and their buffing system is so simple and easy.
Whether you have 1200, 1500 or 2000 grit sand scratches start with Ultra Cutting Creme and a cutting wool pad. One quarter size glob centered in the center hole of your wool pad is usually sufficient for a 2'x2' area (don't shoot lines of compound all over the hood like 3M). Wool pads like speed so I run this setup between 1800-2400 rpms. Hold the pad flat when you can. Usually after 6 passes (varying the direction of course) you have removed most if not all of your scratches. Ultra Cutting creme is intended to remove all scratches before switching to Polish. Buff the surface clean.
Once all scratches are removed you will have roughly 80-90% of your final gloss. At this point, switch to a polishing foam pad and Ultra Polish aka Presta 1500 Polish (old name). Run the foam polishing pad between 1200-1600 rpms working a 2'x2' area (only need about a dime sized amount for this) at a time. This is the 2nd and the last step. For more and more gloss such as a show car/restoration keep repeating this step. Polish the surface clean. If the surface feels greasy after you finished you used way too much polish.
Presta is body shop safe, easily washes out of jambs even days later, uses minimal amounts of product and is dirt cheap compared to anything 3M makes.
Their Fast Wax (the original NON VOC Compliant version) is easy on easy off for a fast wax job that will allow fresh paint to breath.
Let me reiterate that Presta is simple, fast and inexpensive.
