Jen’s Take

RUPES D-A Coarse is one of those compounds that earns a permanent spot on the shelf because it delivers strong correction without fighting the product. When a vehicle comes in with heavier wash marring, oxidation, or sanding marks, this is a go-to first step for fast, controlled defect removal.

The lubrication system gives it a smooth, predictable polishing cycle, so it doesn’t dry out or dust all over the panel like old-school heavy-cut compounds. You get the cut you need plus a surprisingly clean finish, which makes it easy to follow up with a refining polish or, on some paints, even run it as a one-step.

Key Benefits

• High-performance cutting compound for moderate to severe defects
• Smooth, lubricated polishing cycle for better control and longer working time
• Low dusting formula to reduce cleanup between sections
• Finishes cleaner than most heavy-cut compounds on modern clear coats
• Ideal first step before ceramic coating or protection

Best Uses

• Removing sanding marks (with proper pad and technique)
• Leveling heavier wash marring and random isolated deep scratches (RIDS)
• Correcting oxidation and neglected paint
• First step in a multi-stage paint correction
