This will be for a Barrique Red Metallic '07 335i...it looks great from most angles, but up close you can definitely tell it went through many a dealership carwash w/ the previous owner

As you can see, the hood took most of the abuse, but luckily the rest of the car only has minor swirls and thankfully even the worst looking ones aren't deep enough to catch your fingernail. Every imperfection on the car looks much worse now given that it has a fresh coat of Meguiar's NXT though (wax filled into all the swirls) too.

Anyway, after reading a ton of reviews, most all of the Menzerna stuff looks nice. The Menzerna Micro Polish SF 4500 (PO85RD) looks good as a 2nd or 3rd step polish, but I'm not sure how aggressive I should start given the current condition of the paint and my color paint in general: PO83? PO91E? Or maybe M105/M205 from Meguiars?

Also, which is a better LSP: Black Fire Wet Diamond or Menzerna Power Lock?

Thanks again!

I would probably suggest a two step polishing process with either combination:

M105/orange
M205/white

OR

Menzerna SI1500/orange
Menzerna SF4000/white

These two steps are usually enough to remove the majority of the imperfections and bring back a deep gloss. If you want a little extra optical clarity you can follow up with the SF4500 and a blue pad, but it's almost never necessary.

Afterwards protect with either the BFWD or the Menzerna Power Lock as you mentioned with a clean blue pad. Both are exceptional but I give a slight edge to the BFWD for some extra gloss. You can't go wrong either way and you'll love them both. Upon completion the paint should look a lot better and be well protected for months to come!
