Chemical Guys V38 Optical Grade Final Polish

V38 is a final-step finishing polish that removes 2500–3000 grit sanding scratches, swirls, and holograms using aluminum oxide and diatomaceous earth abrasives in a water-and-isoalkane carrier. Amazon reviews consistently describe permanent correction rather than filler concealment. Apply a few drops to a finishing pad, work by hand or DA with a light water mist to extend open time, then wipe off with microfiber — forgiving enough for first-timers; one verified reviewer (13 helpful votes) documented hand-only correction on a quarter-size haze spot in 20 minutes. Amazon: 4.7 stars / 525 reviews; multiple users confirm correct two-step behavior. CCT score: 7.1 (Recommended).

Two-step detailers coming off a compound pass, especially those working on ceramic clear coats or in paint environments where silicone contamination is a concern. Skip it if you're expecting one-step correction on deeper scratches; compound first, then come back to V38.

WARNING signal word from a mild eye irritation code (Cat 2A) in SDS §2; eye protection is warranted during machine application. No skin PPE applies — the only dermal code in §2 is Cat 5, which carries a health-score deduction but falls below the PPE trigger threshold. No respiratory PPE indicated; ventilate an enclosed garage as standard practice given the isoalkane carrier. VOC is 45 g/L (CARB-compliant); residue wipes to microfiber, no drain pathway, no aquatic toxicity codes in the SDS.
