For buffing metalizer, I like either socks or kleenex. Note though: the window for buffing is short. Metalizer dries VERY fast. 5 mins may be too soon to start buffing, 10 mins may be too late. In my experience though, it's usually about 10 mins to start buffing lightly, then a few minutes later (after it's fairly shiny) you can start buffing harder.
Highly buffed titanium looks AWESOME. I'll try to photograph my F-18 nozzles I did that way. Unbuffed titanium is basically "metallic grey", a bit of buffing adds iridescence, highly buffed looks browner.
I only slightly buffed the interior of my VF-25 nozzles, here's a pic:
(it's basically unbuffed)
