OK... speaking as a newbie here:
I've seen the Hampshire Sheen range on youtube too. It sounds interesting and I might give the High Gloss a go.
When I started out I used a paste wax/applied on the lathe method, as this guy does. It was OK, and quite impressed me as a beginner. My tutor introduced me to the three-stage buffing process (triple-E/Diamond white/wax stick) and for me at least it gives a far superior finish. My 'customers' (relatives, friends and neighbours) definitely noticed a step-change when I went from paste waxing to buffing. But it does add a significant extra stage to the turning process, so if I could go back to applying a finish on the lathe that gets me somewhere near a buffed finish that is of interest.
Having said that, I'm in no hurry - I'm a hobbyist, not a production turner, so the extra half an hour or so with the buffing wheels is no big deal for me.
