You're probably going to have to cut the paint with a light compound.
P21S should be used only on paint that's not oxidized so if you clay, cut, polish, and seal - then it should be ready for the wax. It won't look very good on oxidized paint, but it will look outstanding on freshly polished paint! P21S is one kind of wax I use, but it won't last long, that's why I recommend some kind of paint sealant beneath it, which should last around 4 months.
Don't use "cleaner waxes" Use a multi-step system, since you're newer to the detailing scene I would recommend trying mothers 3-step first - as it is non-abrasive and really simple to understand and use. The reason I recommend this is because if this removes enough oxidation after you apply the first two steps you should be okay, but cutting the paint would be the most effective - just not for someone new just yet.
Make sure you do this all (except applying the waxes) with a machine though, otherwise the polishes won't be effective.
