Chemical Guys C4 Clear Cut Correction Compound 16 oz — Fast-Cut Scratch & Swirl Remover

Chemical Guys C4 Clear Cut Correction Compound is a professional-grade, fast-cut polish that removes scratches, swirls, oxidation, and holograms to restore smoothness and gloss to automotive paint.

This 16 oz formula is built for detailers and enthusiasts who need efficient paint correction without sacrificing finish quality. Using advanced abrasives, C4 attacks heavier defects yet breaks down to a clear, refinishing surface so you can move quickly from correction to protection. It’s compatible with common polisher types and most modern paint systems when used according to instructions.

How quickly will C4 remove visible scratches and swirls?

C4 is engineered for high cutting action, shortening the time it takes to eliminate moderate to heavy surface imperfections. On a dual-action or rotary polisher, you’ll typically see defects diminish within a few passes, with the compound shearing down to a refined surface.

• Fast-cut abrasive formula targets heavy swirls and light scratches
• Breaks down cleanly for a clearer finish, reducing follow-up steps
• Works with dual-action, rotary, and long-throw polishers

Will C4 work on my vehicle’s paint type?

C4 is formulated to be safe on clear coat, single-stage, and many ceramic-enhanced finishes when applied properly. It restores depth and reflection across colors without discoloring, but always test a small area first to confirm compatibility.

• Suitable for clear coat and single-stage paints
• Can be used on ceramic-coated vehicles if following instructions
• Recommended spot-test to confirm desired cut and finish

What tools and pads are best with this compound?

C4 pairs well with a range of machine polishers and pads depending on the job’s severity. Use cutting or medium-cut foam or wool pads for heavy defects, then refine with a finishing pad if you want an extra-clear gloss before sealing.

• Dual-action polishers for safer, user-friendly correction
• Rotary or long-throw machines for faster stock removal by pros
• Cutting foam or wool pads for defect removal; finishing pads for gloss

How should I apply and finish after using C4?

Apply a small bead to the pad, work at a moderate speed, and make overlapping passes until the compound diminishes. Wipe residue with a clean microfiber, inspect the surface, and follow with a polishing or gloss-enhancing product plus paint protection for longer-lasting results.

• Apply sparingly—less product often yields better control
• Work until the compound breaks down, then remove residue with microfiber
• Finish with polish/sealant or wax for lasting protection
