Meguiar's Last Touch Spray Detailer (D155)

Meguiar's markets the D155 family as both. Applied neat it works as a quick detailer for removing dust and fingerprints; diluted 1:1 with water in a spray bottle it works as a clay lubricant for use with a clay bar or mitt. The 1-gallon D15501 is the professional refill format and the 1:1 clay-use dilution is the brand's stated recommendation. The 32-ounce DRTU15532 sibling ships ready-to-use in a trigger bottle. CarCareTruth scores this listing against the clay-lubricant rubric because that is the clay-use case under review.

California's Proposition 65 is a labeling regulation that operates independently of the OSHA/CLP hazard classification system. A product can be classified as not hazardous under the safety data sheet rules and still require a California label if any ingredient is on the state's list at any detectable level. The REACH/CLP SDS reviewed here is the UK/EU document and does not address the California regulation. The product listing carries the warning, which is reflected in the health score.

Meguiar's recommends diluting the D155 concentrate 1:1 with water for clay-bar use, as stated in the product listing and brand documentation. The dilution preserves clay grab on bonded contamination while providing enough glide for the bar to move safely across the paint. Used neat as a clay lube, the product can over-lubricate and cause the clay to hydroplane over heavier contamination rather than picking it up.

Meguiar's markets the product as universally surface-safe. No named third-party paint protection film, vinyl wrap, or ceramic coating manufacturer endorsement has been located in public sources. The mild chemistry (water-dominated, IPA at <2%, no aggressive solvents) is consistent with safe use on coated and wrapped vehicles based on the ingredient profile, but the surface-safety claim is a brand statement rather than a third-party-validated specification. Test on an inconspicuous edge first if the vehicle is wrapped or freshly coated.

Yes. The water-based formula provides lubricity that is brand-neutral with respect to the clay product. Community reports support its use with a range of consumer and professional clay bars at the 1:1 dilution. Meguiar's bundles their C2000 Mild and C2100 Aggressive professional clays in their own kits, but the lubricant chemistry is not coupled to those clay grades and works with other brands.
