I've typically used Meguiars. It seems to leave little or no microscratches in the paint on my cars. The RV I'm not so concerned about that with the white finish-clean and shiny is my goal-not micro detail. But that's what I have on hand so I use it. Definitely like Ultimate Quick Detail and only use the cleaner wax as necessary. The Quick Detail seems to bead water as long as anything provided the finish is in good shape. In fact I haven't found too much difference in nearly all the cleaner wax products I've used as far as water beading goes. Meguiars just seems to be very paint friendly from a scratch standpoint.
