Diamond dust ( grit ) is in a oil based matrix such as Vaseline. This is because diamond sticks to the oil and thus allows a surface of it to exist. Alumina oxide generally is suspended in water based solutions on a polishing lap. The Kit "scratch out" says not to get on paint, so I gather it is a wax/petroleum based, but I am not sure. I guess any kind of light random movement would do. I would just take it along with me when I go walking and move it between my fingers. Again, this is an experiment, nothing promised.
