From the manufacturer’s Safety Data Sheet, Section 8
“SDS §8 specifies gloves for prolonged or repeated skin contact. The liquid format makes incidental drips during application more common than with paste wax. No H315 or H317 in SDS §2 at the mixture level; the situational tier reflects the SDS §8 specification, not a GHS hazard classification.”

TL;DR Holds up 6-8 weeks on a daily driver, at the liquid-wax category median, with a notably easy one-pass buff-off that works even on a warm panel. Real carnauba-and-polymer blend; the finish has mild carnauba warmth rather than dramatic depth.
A carnauba-and-polymer blend that leaves a clean, slightly warm gloss. Pour onto the included foam pad, spread one panel at a time, let it haze 2-5 minutes, buff off in one pass with no pressure needed. Community sources (r/AutoDetailing, AutoGeek forum) confirm 6-8 weeks of visible beading on a daily driver washed weekly; garage-kept cars can see 3-4 months. The label claims "strong, long-lasting protection" without specifying a duration; the community window is the honest number. Carnauba character is present but mild; the result is clean and polished, not deep or dramatic.
Buy this for a no-fuss quarterly maintenance wax that goes on fast and looks good; works for any experience level on any glossy paint. Skip it if you want 3-4 months of protection per application: a paste wax or paint sealant lasts significantly longer. Skip it for show-car carnauba depth: a pure-carnauba paste wax delivers warmer, more dramatic gloss at the cost of heavier application.
EU SDS §2 classifies the product as non-hazardous, with no GHS signal word at the mixture level. SDS §8 specifies gloves for prolonged or repeated skin contact; SDS §8 states eye protection is not required. Amazon lists a Prop 65 warning for trace petroleum-distillate constituents (C11-C14 isoalkane fractions), a California disclosure requirement. Leave-on product; estimated VOC 51-150 g/L from SDS §3 petroleum-distillate fractions, reduced by the x0.75 leave-on pathway modifier.
