Chemical Guys InSynchro V45 Medium Cut Car Polish 16 oz — Removes Light Scratches & Swirls, High-Gloss Finish

Chemical Guys InSynchro V45 is a medium-cut finishing polish that removes light scratches and swirls while restoring high-gloss clarity.

Built as the second stage in the InSynchro correction system, V45 bridges heavy compounding and final protection. Its balanced abrasives refine the micro-marring left by stronger compounds and lift haze to reveal deeper color and reflectivity. The formula works smoothly with dual-action and rotary polishers, offering detailers and enthusiasts a reliable step toward showroom-quality shine without excessive rework.

How does V45 improve paint after compounding?

V45 is formulated to take out the fine defects compounders leave behind—light scratches, swirl marks, and hazing—while building gloss and depth. It removes imperfections efficiently so you spend fewer passes to reach a polished look, and it conditions the surface for sealants, wax, or ceramic topcoats.

• Medium-cut abrasives smooth micro-marring left by heavier compounds.
• Improves reflectivity and color saturation for richer appearance.
• Reduces need for repeat polishing by delivering consistent removal.
• Prepares paint for long-lasting protection layers.

Which tools and vehicles work best with this polish?

V45 is versatile: safe and effective with both dual-action and rotary polishers, and suitable for a variety of vehicles including cars, trucks, motorcycles, and RVs. Choose the pad and speed appropriate to the level of defect and the machine type to maximize removal while preserving finish quality.

• Compatible with dual-action and rotary polishers for professional flexibility.
• Use medium-density foam or microfiber finishing pads for best results.
• Applicable on painted metal, clear coat finishes across many vehicle types.
• Works as a follow-up to heavy-cut compounds for staged correction.

What results can I expect after using V45?

Expect noticeably improved clarity and gloss with fewer visible swirl marks and light scratches. The polish produces a smooth, reflective surface that enhances color depth and delivers a showroom-style look ready for final protection products.

• Reduction of light scratches and swirl marks after a single pass.
• Enhanced mirror-like shine and deeper paint color.
• Smoother surface finish that bonds better with sealants and waxes.
• Consistent, repeatable outcomes across different panels and vehicles.

How should I use V45 safely and effectively?

Start by removing heavy defects with a cutting compound, then switch to V45 to refine the surface. Work in small sections, apply moderate pressure, and finish with a clean microfiber towel; always test on an inconspicuous area first and follow pad and speed recommendations for your polisher.

• Use after a heavy-cut compound (for example, V43) as the second correction step.
• Apply to a pad, work 2–4 minutes per panel depending on defect level.
• Wipe residue with a clean microfiber towel; inspect under good light.
• Seal with wax, sealant, or ceramic coating once desired clarity is reached.
