Recommendation for good polish?

menzerna and wolfgang (made by menzerna) are good.
it all depends on what you are looking for, budget, your skill level, etc.

Can't go wrong with Menzerna.

I use the PF2200, SF4500, PL-88 and top it off with Wolfgang Fuzion.

They do have 2 other polishes with a different cut/gloss. Either way, if you "polish" with the 5-7 cut, you'll want to follow it up with SF4500; which really helps give the clear coat a glass look. You can also vary the cut effectiveness with the pad selection, in conjunction with an orbital. I pair the PF2200 with an orange Lake Country, SF4500 with a white, PL-88 grey and Wolfgang with a yellow.
