Gus prefers three compounds for the various steps in the rub-out process, as each compound performs a different function. The first cut is done with a rubbing compound, which eliminates sanding scratches. A buffing polish is used to eliminate swirls from the rubbing compound. The last cut is done with a polish and a foam pad, which removes all polishing marks and swirls. The final step is hand polishing with a super-fine glaze. This fills minute polishing scratches and adds additional luster to the surface.
