Bobby G, who's got more experience than I with the PC 7424XP probably hit on another important key with the PC7424XP, two things he noted-made mention of, 1., the larger pads, and 2., the PC does not work effectively at lower speeds like 3.5 to get consistent rotation like a Flex, and do any meaningful paint correction.
Through all the articles I have combed through in the past 2-1/2 or so months here, folks here seem to say, and basically all agree, a wax-sealant applications at 3.5, OK, that it doesn't require rotation to lay down, or remove a wax-sealant, (if you choose to use the PC in such a manner) but for paint correction, there's only going to be two speeds, 5, or 6 that will work properly. BTW, there is no in-between 5-1/2 speed with the PC7424XP, it is either 5, or 6, they did not index the speed adjustment wheel in betwen those two speeds I've found.
Bobby, and many many others all seem to agree, the sweet spot with the PC7424 is a Lake County 5" backing plate, and 5.5" pads, nothing larger. Another good option, like I myself have, is the 3.5" Lake County Backing Plate, and 4" LC CCS Pads for working smaller areas.
Mike Phillips has repeatedly made note of liking flat pads over other convoluted, dimpled, or other types of pads for basic paint correction.
Again, hope this helps, my post here is basically a re-hash-repeat of what those in the know here have learned-shared, and am just again passing this info onto you. Mark
