Menzerna Heavy Cut Performance Compound 400

The Menzerna Heavy Cut Performance Compound 400 removes scratches and sanding marks down to 1200 grit in short polishing sessions. The diminishing abrasive formula breaks down during use, allowing you to go from heavy correction to an acceptable gloss level without a separate finishing step. That makes this compound suitable for the weekend detailer and the professional polisher alike.

Why it works

The ultra-fine abrasive breaks down as you polish, leaving the surface uniformly finished and eliminating the need for a separate light polish on minor defects. Pair with a wool cutting pad for maximum correction or a heavy cut foam pad when you want a bit more control over the final result.

What's inside

1 bottle Menzerna Heavy Cut Performance Compound 400, 250 ml, ready to use, do not dilute.

Why this product

• Cut 8 / Gloss 7: removes sanding marks down to 1200 grit and leaves a respectable gloss level right away

• Diminishing abrasive: the grit breaks down as you polish, no separate finishing step needed for lighter corrections

• Wide machine range: works on rotary (800-1500 RPM) and DA machines (speed setting 3-5)

• Clear visual cue: compound turning transparent signals correction is complete, no guesswork

• 250 ml per bottle: efficient dosage of 3-4 drops per pad per section

How to use

1. Shake the bottle and apply 3-4 drops (pea-sized) onto the pad (Spread the compound at low speed across the panel before starting the machine to avoid product waste and splatter)

2. Rotary: set 800-1000 RPM and work with firm pressure; DA: speed setting 3-4 (Work in overlapping passes, first horizontal then vertical, 4-6 slow passes per section of roughly 50x50 cm)

3. Increase speed and reduce pressure in the final passes (The compound is done when it changes from milky white to transparent or lightly oily)

4. Remove residue immediately with a clean microfiber towel and inspect the result (If deep scratches remain, repeat with a fresh drop; for light remaining haze switch to a medium pad)

Pair this compound with the right microfiber towel for residue removal and a clay bar to prepare the paint surface beforehand.
