I actually used Megs soap. I think it lasted 2-3 washes and the beads were like big puddles and starting to spread far apart. It also didn't look like it was freshly waxed after it was washed. I did like the NXT, but I would have to wax every other wash to keep it looking like I wanted it to look. Now that I use Zaino polish, the beads are super small and really tight together, I mean theres thousands of beads everywhere, and after I wash, it keeps that freshly waxed look. I have 4 washes now on the two coats of Zaino, and it still looks like it was just waxed and is super slick.
