Yeah, I concur with what has been said. 499 used a different binder from the beginning when Ampex first introduced it, so no sticky-shed. In my experience it tends to shed a powdery oxide more than other tapes, but gets better with use. I don't use it now, but when I did I had to clean my tape path more often. All tapes shed a little oxide, some more than others. I've never seen a sticky-shed reel of 3M 996 either, but just high-normal oxide shedding. Quantegy GP9, which is based on 3M 996 is the cleanest running tape I know of.
