I've used IP, FPII, FTG, and FMJ with excellent results.
The FMJ goes on easy & comes off even easier and, so far, I thing it's worth the price. 1st layer was done with a PC & white LC pad, 2nd & 3rd layers were done with a MF applicator. Residue was removed with a couple MF towels & great results obtained from applying either way.
The only other observations I can make are the water beads tend to get loose quickly, still beading but they look weird. Kind of like the difference between a perfect sunny side-up egg (any top quality carnauba) & an a yoke that breaks soon as it hits the pan.
FMJ will tend to smear if a dribble of water runs out of some trim but it's easily corrected with some more FMJ on a clean dry pad/applicator.
FMJ will also stain your pads/applicators so be aware.
