It works with high-speed rotary buffers for fast material removal and avoids waxes, fillers or silicones so subsequent polishing and coating steps bond cleanly. The water-based formula also makes cleanup simple and reduces solvent odors compared with solvent-heavy alternatives.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly will this remove P800 grit and heavy sand scratches?\u003c\/h3\u003e\n\u003cp\u003ePresta Super Cut Compound is formulated for aggressive cutting, so it removes P800 and finer sanding marks in far fewer passes than light polishes.
