Sure, if you want your hand to fall off, wax on wax off for hours on end lol. OP has extremely long work times, not a quick breakdown product to be used by hand. I never saw any staining of trim from it, just if your using a machine remember to tape trim off as the pad can burn trim.
Scratch-X is ok if you need to do a small spot by hand, not a whole car. Good for areas like under door handles etc.
