On the subject of MF applicators, check out the ones in the Autopia store. They are excellent. Plush, no seams, quality sponge, etc...
I bought 4 of them.
They are the best MF applicators b/c they are small and can fit in jars of wax.
I used a foam applicator for NXT.
I like MF pads for paste waxes.
It's a matter of taste.
