Platinum Blue Polishing Compound
Use for pre-polishing and cutting down of platinum and other metals. Also for final polishing on acrylics.
When using the buffs, attach to the tapered spindle. As it is spinning, hold the bar to the buff so that it puts a light coating on it (a few seconds). When changing bars, clean off the coating on the buff with a soft cloth as best as you can. These should be used dry.
