Just thought in light of recent discussions on this issue, I`d post up this amazing work I saw over at another site.

91 hr extreme detail by Immaculate Reflections - extremely pic heavy 280+ beware - Autopia.org

I don`t have anything to do with the poster or the vehicle, but give him all the credit. This is some amazing, labor intensive work.

No way you can wetsand like this (correctly) in 2-3 hours. {The wetsanding alone took 55 hours on this particular resto} No way you`d have gotten all of that out just using polish and a polisher - not effectively anyway. Wetsanding is the most efficient way I know of to remove bad marring and defects as well as orange peel.
