To Wetsand or to Compound?

3M makes an excellent air sander, they even have a pretty cool kit that fits in a box. You can 3000 grit a whole car pretty quickly and it really brings out the paint if there is enough thickness left to sand.

In my experience speaking with some body shop sanding pros, they don't recommend sanding an entire car if it's OEM paint. It's bound for failure within a year or so.
Too much UV protection is removed by taking off so much CC.

Yet, spot sanding apparently is safer than compound if done CORRECTLY.
