Thread: Why Greaseless buffing compound

Early compounds (rouge, Tripoli, CrOx, etc. ) were/are held together with grease or wax.
Greaseless compounds are held together with a glue (thus greaseless) and that glue helps the compound stick to the wheel better.

Greaseless compounds come in a wider range of grit sizes than greased ones and the greaseless grit sizes are more uniform and controlled.

I use the greaseless compounds below 1000 grit, then usually switch to the "greased" CrOx
