Ardex Smart Cut Compound 4225

Body-Shop Cutting Compound That Finishes Bright

Ardex Smart Cut 4225 is a professional machine rubbing compound built for body-shop production cutting and serious correction work. Its cut sits between Ardex Alpha Grit and marine Super 600, so it removes deep scratches and sand marks in a single pass yet still finishes bright. Made for detailers and shop technicians who need fast defect removal without chasing extra polishing steps.

Key features

• Aggressive, balanced cut for deep scratches, sand marks, and 1200-2000 grit sanding scratches
• Removes heavy defects in one pass to speed up production cutting
• Finishes bright, reducing the haze and swirling that slows down follow-up polishing
• Cut level positioned between Ardex Alpha Grit and marine Super 600 for versatile correction
• Engineered for high-speed buffers with wool or foam cutting pads
• Trusted Ardex Laboratories formula backed by decades of automotive reconditioning experience

How to use

Work on a clean, cool surface out of direct sunlight. Shake well, then apply a small amount of Smart Cut to a wool or foam cutting pad on a high-speed buffer. Work a 2 ft x 2 ft section at a time using moderate pressure and overlapping passes until the defects are removed, keeping the pad flat and the surface cool. Wipe the residue with a clean microfiber towel and inspect, then follow with a polish or glaze if a deeper gloss is desired. Avoid letting the compound dry on the paint, and keep the pad clean for consistent cutting.
