Lake country light cutting and polishing foam pads, i would think 2 of each would get you through 1 car
I would order a conditioning brush to scrub pads after each panel
Buff N Shine 50/50 euro fiber pads may get the job done in 1 shot ( likely with the "polish" not the "compound" from Adam's )
3-4 of these because the fibers will get more "gummed" up even using the brush after each panel.
If you have a compressor and can "blow out" the pads, this would be the best option
Shake the chemicals, they should be fine after 1-2 years.
Always start with the least aggressive combo. For example, a polishing pad and the polish.
do one area and see how it comes out. If you are happy with the results, there is no need to hammer down on the paint with the compound + more aggressive pad.
Some areas may require the compound but only use it as needed.
If you can attain 80-85% correction with the polish and polishing pad, I would say that is a WIN.
