Orbital polisher? I have never heard great things about them to be fair... Always thought they were a bit of a gimmick lol.
Personally the Menzerna products will have a slightly higher cut than I would like, if using with a DA or rotary.
I used the Menzerna on my BMW, incredible products and amaxing results on the slightly harder BMW paint. But the Zed I would use something less aggressive depending how badly worn the paint is, I am just on the CleanYourCar forums now asking for opinions, I think I will try Auto Finesse Revitalise on my Zed.
As for pads, Menzerna pads are harsh again. Try Lake country pads or Auto Finesse pads?

Scholl S17+ or 3M Extra Fine (yellow top) should be right up your street. Grab a rotary and the 3M yellow pad. Grab a Chemical Guys Hexlogic Orange pad in case you need to step up the grunt.
That'll do you proud.
Questions? Jump back in with 'em.

Another combination to try!
