I just bought what I think is the DACP that you guys talk about but when I went to Meguiar's website the bottle looks different and it doesn't have that number #83..
There's an older label design too, where there's a graduated shaded area on the right and a little arrow pointing it out in about the same spot. Maybe that's the one you saw.
Using a compound with a tool that does break it might create swirls in stead of removing them. The PC is very gentle, I use it with the DACP after the rotary w/ compound, to remove buffing marks and to prepare the surface for the final polish.
