Depends on how hard the paint is. In my experience the GEPC only cuts *very* soft paint (and only when used with a polishing, not finishing, pad), but it does do a little filling. I follow 1Z PP with 1Z (pro) MP. That's the progression I'd use if worried about micromarring from the PP. IMO the GEPC is too mild for this, it didn't even do much on the very soft paint on my Jag.
