Nu Finish is famous for shining up pretty much anything and lasting a long time. Beats anything else for durabilty. Can be hard to buff off if you do too much at one time. Stick to 2x2 areas and go slow.
Here's from an AutoGeek forum:
Meguiar’s NXT Generation Tech Wax 2.0, $18, and NU Finish NFP-80, $8, A CR Best Buy, topped Consumer Reports’ latest tests of 19 car waxes, for liquid and paste, respectively.
CR’s tests also revealed that premium car wax brands don’t necessarily out-perform their lower-priced counterparts: Liquid or gel waxes from premium brands like Autoglym, Eagle One, Mothers, Zymol scored lower than products from Nu Finish, and 3M, although Autoglym Super Resin Polish (liquid) and Mothers California Gold Carnauba Cleaner Wax (liquid) were both Recommended. Among paste waxes, Mothers FX Engineered Synwax 20011 (Recommended), and Mothers California Gold Carnauba Cleaner Wax were outscored by Nu Finish NFP-80 and Turtle Wax Synthetic Paste Polish T-465.
I'd stay away from Meguiars NXT as I've found it looks great but doesn't last. However, their Ultimate Compound is the best there is for cleaning up ugly paint!
PS: Don't waste your money on "airplane" waxes.....same old stuff - different bottle - higher price!
