Chemical Guys P4 Precision Paint Perfection Polish 16 oz — light-to-moderate scratch & swirl remover, safe on clear coat

Chemical Guys P4 Precision Paint Perfection Polish is a professional-grade 16 oz polish formulated to remove light-to-moderate scratches, swirls, and towel marks while restoring gloss and clarity to all automotive paint types.

Engineered for both detailers and enthusiasts, P4 (GAP11716SW) blends refined abrasives and finishing agents to refine paint finish without aggressive clear coat removal. The formula is compatible with single-stage and clear coat paints as well as ceramic-coated surfaces, making it a versatile choice when you need efficient correction and high-gloss results. Use it by hand or with a machine—dual-action polishers and rotary buffers both work well—so you can tackle quick spot fixes or full-panel restorations.

How effectively does P4 remove scratches and swirls?

P4 targets light to moderate imperfections by combining micro-abrasives and lubricants that break down blemishes while protecting paint integrity. It reduces visible swirls and light scratches and improves surface uniformity, delivering smoother reflections and deeper gloss in most multi-step polishing workflows.

• Removes light-to-moderate scratches, towel marks, and swirl patterns
• Produces a refined surface ready for finishing polishes or protection
• Safe on clear coat, single-stage, and many ceramic finishes

What tools and techniques work best with P4?

P4 is formulated to perform with hand application, dual-action polishers, and rotary buffers, giving flexibility depending on experience and the job size. For beginners, a dual-action polisher with a medium-cut foam pad provides controlled correction; experienced users can pair it with a rotary buffer and finishing pad for faster results.

• Hand application: small spots or delicate areas
• Dual-action polisher: balanced correction and safety
• Rotary buffer: faster cut for experienced detailers
• Follow with a finishing polish or sealant for lasting protection

Will P4 damage paint or affect ceramic coatings?

P4 is engineered to be paint-safe when used as directed and does not aggressively strip clear coats. It can be used on vehicles with ceramic coatings for mild correction, but on heavily protected finishes perform a test spot first and consider following with a maintenance-specific product to restore hydrophobic properties.

• Formulated for compatibility with most modern and classic paints
• Perform a small test area if the vehicle has recent or unknown coatings
• After polishing, reapply protective sealant or ceramic topper as needed

How do I get the best results from a 16 oz bottle?

A 16 oz bottle of P4 covers multiple spot repairs or several panels depending on the correction level. Apply sparingly—less is often more—work the polish at recommended speeds, and wipe off residues with a clean microfiber to reveal the recovered gloss. For large jobs, combine P4 with a finishing polish and a quality sealant to extend shine and protection.

• Use short work sections and test polish pressures/speeds
• Wipe with clean microfiber towels and inspect in good light
• Finish with a paint sealant or wax for durability

Who is this for: Chemical Guys P4 is ideal for DIY car owners, weekend detailers, and professional detail shops who need a dependable polish that balances correction and finish. If you want to remove light-to-moderate imperfections while preserving paint integrity and achieving glossy, reflective results, this 16 oz polish is a practical addition to your detailing kit.
