Chemical Guys InSynchro V45 Medium Cut Car Polish 16 oz — Removes Light Scratches & Restores Gloss

Chemical Guys InSynchro V45 is a 16 oz medium-cut polish engineered to remove light scratches, swirl marks, and haze while restoring deep gloss and clarity to automotive paint.

Built as the second step in the InSynchro correction system, V45 bridges aggressive compounding and final finishing. Its advanced abrasive formula refines the surface after heavier compounds, producing mirror-like shine with fewer passes. V45 works with both dual-action and rotary polishers and is formulated to be user-friendly for professionals and enthusiasts who want dependable correction without sacrificing finish quality.

How does V45 improve paint after heavy compounding?

V45 is designed to take out the micro-marring and light defect patterns left behind by heavier cutting compounds. It polishes the paint to a smoother, more uniform surface that reflects light more evenly, enhancing depth and color vibrancy.

• Removes light scratches, swirl marks and haze from prior compounding.
• Balances cutting mechanics with polishing for fewer repeat passes.
• Prepares the paint for sealants, waxes, or ceramic coatings.

Which tools and surfaces work best with this polish?

V45 is versatile across tooling and vehicle types: it performs well with dual-action polishers for safer, user-friendly correction and can also be used on rotary machines for faster refinement by experienced users. The formula is safe on automotive clear coats found on cars, trucks, motorcycles, and RVs when used as directed.

• Compatible with dual-action and rotary polishers for different skill levels.
• Safe on clear coat finishes when used with correct pads and techniques.
• Suitable for a range of vehicles including cars, trucks, bikes, and RVs.

What results should I expect after using V45?

After using V45 you can expect a noticeable reduction in fine imperfections and a higher-gloss, clearer finish that brings out paint depth. The polish is formulated to leave a smooth surface ready for protective layers, reducing the need for repeated polishing passes.

• Improved reflectivity and color depth for showroom-quality appearance.
• Smoother paint surface that accepts waxes and coatings evenly.
• Efficient correction that minimizes time and effort during the finishing stage.

How should I use V45 for best performance?

Apply a small amount to a clean polishing pad or directly to the panel and work in sections, using overlapping passes until the defects diminish. Finish with a clean microfiber towel to remove residue, then follow with your chosen protection step such as sealant, wax, or ceramic coating.

• Start with a clean, decontaminated surface and correct heavy compounding first (V43 stage).
• Use light to moderate pressure and inspect results often to avoid overworking.
• Wipe off residues and apply a protective product to lock in gloss and durability.

Who this is for: Chemical Guys InSynchro V45 is aimed at detailers, restoration enthusiasts, and DIY car owners who need an effective mid-stage polish to refine paint after aggressive correction. If you want to remove light defects while boosting gloss before sealing or coating, and you use dual-action or rotary polishers, V45 provides a reliable blend of cutting and finishability to achieve professional-looking results.
