From the manufacturer’s Safety Data Sheet, Section 8
“SDS §8.2.2 lists safety glasses as the specified eye/face protection. No H319 (eye irritation) appears in SDS §2 mixture-level GHS classifications · the §8 specification is a standard precautionary listing, not a hazard classification. The situational tier applies: eye contact via slurry splash is a realistic risk during the wet-sanding step, and compound application at close range creates prolonged exposure.”

From the manufacturer’s Safety Data Sheet, Section 8
“SDS §8.2.2 lists polymer laminate gloves (nitrile for incidental contact) as the specified skin protection. The package label states 'MAY CAUSE ALLERGIC SKIN REACTION' as a precautionary statement. No H317 skin sensitizer classification appears in SDS §2 at the mixture level. The situational tier applies for the compound application step where prolonged contact or splash is possible.”

From the manufacturer’s Safety Data Sheet, Section 8
“SDS §2 classifies H372 · Specific Target Organ Toxicity (repeated exposure), respiratory system · which carries a DANGER signal word. SDS §8.2.2 specifies an organic-vapor/particulate half or full facepiece respirator when ventilation is not adequate. H372 is a chronic repeated-exposure endpoint; the rubric requires H331, H330, or H334 for a required tier. The situational tier applies: H372 and the petroleum distillate carrier support respiratory precautions in enclosed spaces or during prolonged or repeated use.”

TL;DR The compound's petroleum carrier earns a DANGER signal word from repeated-exposure organ-toxicity H-codes; use outdoors or with the garage door open. On performance, the drill-powered three-stage sanding process delivers community-confirmed near-new clarity on even severely yellowed lenses · but the kit does not include a UV sealant, so re-yellowing resumes within weeks unless one is applied separately.
The 3M 39008 targets moderate to severe headlight yellowing that hand-applied compound kits cannot reach. Drill-powered wet sanding followed by rubbing compound removes even heavy oxidation and delivers near-new clarity in 30·45 minutes; first-timers with a household drill consistently report strong results, and the broad owner consensus backs that up. The kit does not include a UV sealant: without one applied after the compound step, re-yellowing resumes within 4·12 weeks in outdoor daily-driver conditions. The restoration is real; how long it holds depends entirely on what you add after.
Best for owners with moderate to severe headlight yellowing who already have a household drill and are willing to apply a separate UV sealant after the process · the three-grit sanding progression handles cases that hand-applied kits cannot. Skip it if you want an all-in-one solution: kits from Meguiar's, Turtle Wax, and Mothers in this price range include UV sealant as part of the package. Skip it also if lenses are physically cracked or pitted · no abrasive kit addresses structural damage, and lens replacement is the right call there.
The rubbing compound SDS (3M Document Group 29-3593-0, rev. February 2022) carries a DANGER signal word · H372, Specific Target Organ Toxicity (repeated exposure) to the respiratory system, driven by the petroleum distillate carrier classified as an NTP Known Human Carcinogen and IARC Group 1 substance under repeated occupational inhalation. The SDS specifies working in adequately ventilated areas; where ventilation is inadequate, the SDS specifies an organic-vapor/particulate half-facepiece respirator. The SDS §8.2.2 lists safety glasses as the specified eye protection for the sanding step. The product carries a California Prop 65 warning. VOC content is 213 g/L (moderate bracket). No PFAS. No aquatic hazard codes confirmed.
No. The 3M 39008 Headlight Lens Restoration System includes abrasive sanding discs (500-grit, 800-grit, and Trizact refining disc), a disc pad holder for your drill, and 1 fl oz of 3M Rubbing Compound. There is no UV sealant or UV protective coating in the kit. Without a follow-up UV sealant, restored lenses will begin re-yellowing within weeks to months, depending on sun exposure. 3M's separately sold 39070 UV sealant or a dedicated headlight sealant from Meguiar's, Mothers, or Chemical Guys is needed to extend the results.
The disc pad holder (3.25-inch) attaches to any standard household drill with a 3/8-inch or 1/2-inch chuck. A corded or cordless drill works; 3M recommends low-to-medium speed (typically 1,200·1,800 RPM) for the sanding steps. The kit is not designed for hand use · the drill is the power source for the sanding discs, and results degrade significantly without it.
Without a UV sealant applied after the compound step, results typically hold 4·12 weeks before visible re-yellowing begins in daily outdoor parking conditions. With a quality UV sealant applied immediately after, community long-term reviews report 12·18 months of clarity in most climates. The kit's rubbing compound step leaves the polycarbonate exposed to UV radiation · UV protection must be added separately.
The 3M 39008 is one of the most capable consumer kits for severe yellowing, specifically because it uses drill-powered sanding to cut through deeply oxidized and UV-damaged coatings. The three-grit sanding progression (500→800→Trizact) removes heavy oxidation that hand-applied compound kits cannot touch. Severely pitted or cracked lenses (physical structural damage to the polycarbonate) are a different problem · no chemical or abrasive kit addresses cracking, which requires lens replacement.
The rubbing compound SDS carries a DANGER signal word (H372 · causes damage to organs through prolonged or repeated exposure via inhalation). The SDS specifies working in adequately ventilated areas and, where ventilation is inadequate, a half-facepiece organic-vapor/particulate respirator. The SDS specifies no respiratory protection is required for adequately ventilated outdoor or open-garage conditions. The sanding step generates polycarbonate dust, for which the SDS §8.2.2 lists safety glasses as the specified eye protection.
