It can be buffed out!?!?!

[Fubar]

I've used it as well and it works fine. I'm not sure how well it would work with an orbital or if it is even intended to be used with one. I think it is mostly intended as a hand application.
My experience with it was to remove a couple of scratches that were a couple of inches in length. I just applied it by hand and it worked just fine in that application.

I was assuming this guy has pin-stripping the entire length of his rig so that is why I've pointed him in the direction of an orbital and its related products.
