multiple slow motion cams would show any impact and effects IMO.
Most if not all BBs already have a surface treatment. A thin layer of something if chosen and applied correctly won't have much effect.
For the purposes of this proposed experiment, the finely-tuned hopup is irrelevant. This is to answer the age-old question of the BB touching the inner barrel during flight.
