Polishing Compounds=Traditional Oil Based and Water Based
Polishing compounds are used for cutting, cleaning and polishing metal surfaces to a final high luster. Different metals and surface conditions require different types polishing compounds.
Polishing compounds are generally broken down into three categories:
- First cut Polishing Compounds are for used for smoothing out rough surfaces and is generally moist
- Medium/Second Cut Polishing Compounds are used for smoothing out semi smooth surfaces, remove less surface material, prepare the surface for the final high luster and is a dryer compound.
- Final Polishing Compound, still removes some surface material, but is minimum. This is the last stage and necessary to produce a high luster.

Polishing compounds are available in two formulas, oil based and water based. Oil based compounds are generally lower cost, will charge the buff faster when applied, work faster and have is the original formula.
Water based polishing compounds, are equal in grit to the oil based compounds, the operator may need to recharge the buff more frequently, but during the ultra-sonic and wash out stage of polishing your parts, water based polishing compounds will break down faster in the buffing compound ultra-sonic solution. It is a good practice, to use different buffs for different metals and polishing compounds to avoid cross metal contamination and unwanted surface scratching during the final polishing stage.
