I remember seeing a post on another forum, with one half of a badly oxidized hood done with AIO by hand, and the other half with a PC, and there was a considerable difference. Thing is, since you're supposed to use a ridiculously small amount of AIO normally, I don't see how using a PC would work effectively, unless you used an excessive amount of AIO (in effect, wasting quite a bit).

Like most things, AIO is not very easy to remove if you put on too much. You can avoid this with a PC if you are good at removing most of the excess using very light pad pressure (in effect--buffing with the applicator pad just after applying and working it in) I made this mistake the first time, AIO and SG require very thin coats, and I put way too much on trying to 'polish' and 'clean'. Now that I know my PC better, its not a big deal.

I would strongly recommend against applying SG by PC. The thin layer is best achieved by hand with a yellow foam using a technique analogous to above. That is, get the product on the paint with moderate pressure and on subsequent rubs use light pressure to remove most of the product.
