Sure, you can go and polish with MZ FPII, just run the PC a bit fast as it has to mimic a rotary as FPII works under heat.
Orange pad is a aggressive pad, step down to a white polish pad.
Or, you could use SSR1 or Pro Polish or Megs Machine Glaze or Hand Polish. With the exception of SSR1, these have oils in them. Same applies for VM. Good glaze, but lots of oil to suspend the glaze. It may interfere with EX-P bonding correctly. You can wash after all the polish or use a mix of distilled water and alcohol to spray and wipe most of the oils away. It just gives EX-P a better bonding surface. Using FPII, although it does not fill, it has a bit more oil so it can be worked longer with say a PC. It's really called "Micro Polish" in the Menzerna line. Does the best job in producing a mirror shine if you know how to use it.
Less headache may be the SSR1/Pro Polish since you plan on using EX-P.
I'vee done my SC430 with Menzerna and EX-P. Took much longer, but if you have the time it well worth it. I used a finish pad on the rotary as I wanted MP (FPII) to burnish the finish and NOT a pad. Washed the car CAREFULLY again, misted with water/alcohol and proceeded with EX-P. Topped with Nattys for a wetter clear look. Then again, EX-P on it's own looks damn good.
I'd use VM on something else if it was my car. Not that there is anything wrong with it, it's just how to match up products best. VM and wax=very wet shine.
