I know a lot of you guys use the buffers and I'm not real familiar with them or what all i need. From my research i have done it seems the best and safest thing i can get is a dual action Porter Cable 7424. My main use for it will just routine polishing and waxing (after clay barring). What pads, backing plates and other stuff should i look at getting? I know there is a lot of package deals out there in the $200+ range but i don't really want to buy a bunch of stuff that i wont ever use. If it means any thing, i would like to still use my meguiares polish and waxes.
