jshillin,
One thing I would add is that a newbie to detailing will always use a PC even after buying a Fles or a rotary. I still use mine on paint that is prone to hologram and in tight small areas as well as headlights. It is very easy for a beginer to start with and as long as they understand to start with the least abrasive product and work up to one that corrects the problem, they will not have an issue.
Flex polishers are great with the forced rotation and I enjoy mine but the PC and the rotary have places in a polishing aresenal. It sounds like we use the same polishes as I prefer Menzerna also and keep Power Gloss, SIP, IP, Final, Micro and Nano polish on hand. I also use Meguiars #105 Ultra cut for REALLY quick cutting, 3M Perfect-it Ultrafine for the really soft paints and still enjoy all of my Poorboy's SSR series. For badly oxidized paint, their Professional Polish is still the best that I have found.
Pads are subjective also and I see where you like Lake, I prefer Edge foam and 3M wool. That is one area that I encourage someone to experiment with as the pads vary in their correction depending upon how the user holds the machine, the polish, speed of rotation, movement, etc. That is what makes the hobby so much fun....
Just wait until he starts asking about waxes....
