<p>[QUOTE=&quot;desertgem, post: 633045, member: 15199&quot;]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 &quot;scratch out&quot; 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.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
