Meguiar's M205 Mirror Glaze Ultra Finishing Polish

Three or four dime-sized drops on a soft foam or microfiber pad, DA at 4,500 OPM, two slow passes per panel section: the residue wipes off clean and the finish holds up to an IPA wipe-down without holograms or filler-mask. Community consensus across Auto Geek, Detailing World, and r/AutoDetailing is that M205 is the polish other finishing polishes get compared against. It runs cleanly across Lake Country, Buff and Shine, and Rupes pad ecosystems with the same result, no proprietary pad chemistry required. Working time is generous and dusting is minimal under typical garage conditions; short flash windows are reported only above 90 degrees F. Quality scores 8.1 out of 10.

Anyone running a two-step paint correction (compound followed by M205) will find this is the de facto reference partner, with the broadest pad compatibility in the category and consistent results whether you're on a soft Honda clear or a hard BMW clear. Also a strong stand-alone finishing polish for lightly defected paint where you want to refine without cutting more clear coat than necessary. Skip it if your paint has scratches that need real compound cut; M205 is a finishing step, not a compound replacement. Skip it if you have a documented MIT/CMIT (isothiazolinone) skin allergy; the preservative is at trace levels but is the driver of the skin sensitizer classification.

The REACH SDS (rev. May 2020) carries signal word WARNING driven by a skin sensitizer classification from a biocidal preservative present at less than 0.002% by weight; no H-codes for eye damage, respiratory risk, or skin corrosion appear in Section 2. SDS Section 8 explicitly states no chemical-resistant gloves and no respirator are required for normal use; situational eye protection (safety glasses) is listed as a precaution for machine application splatter, not a hazard classification. The flash point is 93 degrees C. The Amazon listing carries a Prop 65 warning; the petroleum distillate carrier is the likely trigger. Polish residue ends up in laundry wastewater via the wipe-off towel rather than direct stormwater discharge; no PFAS, no confirmed aquatic toxicity codes.
