Chemical Guys P4 Precision Paint Polish 16 oz — removes light scratches & swirls, restores gloss

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

Whether you’re refreshing a daily driver or finishing a show car, P4 delivers a refined finish that improves clarity and reflection without aggressive cutting. Its balanced formula works safely on single-stage, clear coat, and many ceramic-treated surfaces, making it versatile for hobbyists and pros. You can apply it by hand, with a dual-action polisher, or a rotary buffer for controlled correction and a smoother final appearance.

How will P4 improve my car’s paint appearance?

P4 lightly reforms the paint surface to reduce visible defects and enhance shine. It lifts out fine swirl marks and light scratches, smoothing the clear coat so reflections become sharper and colors look deeper.

• Reduces light-moderate scratches and swirl marks
• Removes towel marks and minor surface haze
• Enhances gloss and reflective clarity
• Leaves a smooth, ready-to-seal finish

Can I use P4 on my car’s ceramic or clear coat finish?

Yes — P4 is formulated for compatibility with single-stage, clear coat, and many ceramic finishes when used correctly. It’s not overly abrasive, so it refines rather than strips, but always test in an inconspicuous area first.

• Safe for modern clear coats and older single-stage paint
• Works over ceramic coatings for light correction
• Recommended spot-test before full-panel use
• Follow with a sealant or wax for lasting protection

Which tools and techniques work best with this polish?

P4 is versatile: use by hand for small touch-ups, a dual-action polisher for controlled correction, or a rotary buffer for faster material removal when needed. Adjust pad choice and speed to the defect severity and paint hardness for best results.

• Hand application for spot corrections and delicate areas
• Dual-action polisher for safe, even polishing
• Rotary buffer for more aggressive correction (experienced users)
• Finish with a clean microfiber and protective sealant

What results should I expect after using P4?

After proper use you’ll notice improved surface smoothness, diminished fine scratches, and increased gloss. The polish leaves a refined surface that enhances color depth and reflection, ready for a protective top coat.

• Smoother surface and clearer reflections
• Reduction in visible swirls and towel marks
• Improved paint depth and shine
• Prepares paint for wax or ceramic sealant
