I've polished fresh paint many times, and the shops I patronize have often polished it (perhaps even wetsanded it) before that.
The important thing is to only use "bodyshop safe" products that won't interfere with the outgassing/curing.
As far as I know, Meg's "80s series" polishes are all bodyshop safe. I also use 3M's PI-III RC (05933) and MG (05937) on fresh paint, as well as Menzerna.
If using Megiuar's stuff, I'd generally stick with #80 (instead of trying the #83), as fresh paint is softer than usual (gets harder as it cures). Even #80 will sometime (micro)mar fresh paint, requiring a follow-up with a milder polish. Had that happen just this last autumn.
No pics, but #80 will usually remove light to moderate marring. It would be an OK product to start with in your situation- what you're dealing with is pretty much what #80 was designed for. But just to be safe, I'd try a small spot (before doing an entire panel) in case the paint is *very* soft.
