Translated from the manufacturer’s Safety Data Sheet, Section 2
H319 (Eye Irritation Cat 2A) in SDS §2 GHS classification warrants eye protection when machine-applying at face/chest height.
U.S. regulatory standard
29 CFR 1910.133(a)(1)
“The employer shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards from… liquid chemicals…”
ANSI Z87.1 (incorporated via §1910.6)
OSHA standards apply to workplaces. Cited here as the U.S. reference threshold for the underlying hazard class.
CarCareTruth publishes the cited sources verbatim and does not advise what action a user should take. Consult the full SDS before use.
Translated from the manufacturer’s Safety Data Sheet, Section 8
SDS Section 8 recommends impervious gloves (rubber, neoprene, or nitrile) for prolonged or repeated contact, and Section 11 reports a possible allergic skin reaction in sensitive individuals (redness, swelling, blistering, itching). That is a genuine hands-on precaution, not boilerplate.

Only when: in enclosed space · prolonged use
Translated from the manufacturer’s Safety Data Sheet, Section 8
SDS Section 8 says general ventilation equivalent to outdoors should be adequate under normal conditions. Section 2 carries no inhalation hazard code (H333 is Acute Toxicity Category 5, the lowest GHS severity tier) and Section 11 reports no respiratory tract irritation, so this is a ventilation precaution for enclosed garages or extended buffing sessions, not a respirator requirement.

California Prop 65 warning
This product's Amazon listing carries a California Prop 65 warning. The manufacturer's Safety Data Sheet (§15) does not list a Prop 65 substance for this product — we show the warning for transparency and flag the discrepancy rather than silently picking a side.
Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.

TL;DR V38 is a water-based, silicone-free finishing polish that permanently removes light swirls and compound haze without fillers · body-shop safe, works by hand or DA.
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. owner 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. Highly rated on Amazon, with multiple owners confirming 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. Impervious gloves (rubber, neoprene, or nitrile) are worth wearing too · SDS §8 recommends them for prolonged or repeated contact and §11 flags a possible allergic skin reaction in sensitive people. No respirator is required for normal use; SDS §8 only calls for good general ventilation, so crack a window or door if you're buffing for an extended stretch in an enclosed garage. VOC is 45 g/L (CARB-compliant); residue wipes to microfiber, no drain pathway, no aquatic toxicity codes in the SDS.
