Hey Oscar,
I really like the Menzerna Line!

rops:
Meguiar's M105 to me seems a little less aggressive than
Menzerna Power Gloss PO34A. That said I think I'd follow it up with
Menzerna Power Finish PO203S.
A nice substitute for
Meguiar's M205, which is a really nice polish, is
Menzerna Super Finish PO106FA. This polish finishes up beautifully and once completed be prepared to be WOW'D...
Not to hijack the thread but I used some Menzerna products last Sunday and took some photos so I thought they'd fit right in here.
This past Sunday I was working on a 2011 Hyundai Elantra. The car was only purchased 3 months ago new and the paint on its horizontal surfaces was really dirty.
From 1/2 the hood!

Menzerna Super Finish PO106FA
I took a shot of the results using
Menzerna Super Finish PO106FA last Sunday. I just started buffing it off with a Microfiber towel and even though there's a few dust particles I think you'll appreciate the results.
I tried to take a good photo but this paint has a really weird flake that reflects light at odd angles.
