I think I might wear a mask if it was me doing the flocking.
Squeezing the air hose to reduce the air flow? My powder coating gun has an adjusting screw to do that, as the powder needs to come out at low speed so that it settles on the piece. The fella in the video seemed to achieve that nicely at the end though, just by feathering the trigger.

The biggest mistake some make in a T25 is flocking/painting parts or all of their dash in a bright colour. The angle of the windscreen reflects it right back at you which I presume is why VW chose matt/silk black finish. Its made worse with dash cams. Silly flockers.
