The finest grade of 3M pad is the light grey colored one, is it not? At least it was the last time I bought any a few years ago and screwed up and bought two whole cases of them- I haven't had to delve into the world of 3M pads since then.
As described above, after knocking the gloss off a finish, old or new, I too use a good furniture paste wax to bring up a nice soft luster. Renn wax is darned good, but so are others, and it ain't rocket science. Just don't use automotive waxes. Go ahead and use a microfiber cloth if you feel you must, but an old soft hunk of flannel will do as well.
