Damn, I love this stuff! I got introduced to it at the Autopia/Meguiars meet out in La-La Land. I guess a more accurate number would be #82.5 since that is where it fits on the Meguiars aggressiveness scale. It breaks down very quickly and you can go straight to a wax if you want as long as you do work it enough to break down the abrasives. Can be used by hand, PC or rotary. Since it breaks down rather quickly, it is probably a better choice by hand than #82 is. I've followed #80 with NXT with real good results and also with Vanilla Moose and EX-P. In fact, my new favorite 3 step is #80/VM/EX-P. Anyway, I thought I would pass this along. I should have some pics to post in the next day or two of cars I have used #80 on.
