DrumDial DDBEC Bearing Edge Conditioner

Decided to give it a try when buying new drumset.
Lubricating the bearing edge is not new to me, I was using car silicone spray or vaseline before that, but the latter could probably harm the drumheads.
The drums are more responsive to tuning and stay in tune longer when bearing edge is lubricated, but be sure to use something like this not to ruin the heads. It has no cleaning properties - the consistency is like lipstick or dry paper glue.
