Oh, then you're absolutely fine! Waxing with the PC is a totally different animal than polishing. You don't have to worry about pressure, rotation, and all that... you're not breaking the product down or attempting to impart change on the clear coat, you're simply spreading a thin coat of product over the surface.
in this video I'm demoing the Flex 3401 which has forced rotation to it, but it should give you an idea of the time/pressure/etc you'll use to apply wax or sealant to the finish by machine... its not much.
