Meguiar's Ultimate Compound

Two-line stripes on a foam cutting pad, a single panel at slow DA speed, then wipe off: the whole panel takes 3-5 minutes. It is a medium-cut compound built around mineral micro-abrasives in a water-based emulsion, documented in community correction threads to clear oxidation and 3000-grit marring on softer clearcoats. Heavy swirls or 1500-grit sanding marks on harder Asian and German clears push it to its limit. Dusting is light under hot or dry conditions and wipe-off is clean even on darker paint. The label's "removes scratches and oxidation" claim is broadly accurate within that tier.

Buy if you are correcting a daily driver: light to moderate swirls, oxidation, or maintenance polishing before a wax or sealant. The forgiving DA workflow and clean wipe-off make it well-suited for first-time paint correction. Skip it if your defects catch a fingernail, if you are working hard German clearcoats, or if you need to remove sanding marks coarser than 2500-grit: Meguiar's M105 or a dedicated heavy-cut compound is the right tool there.

The 2024 SDS classifies this compound as not hazardous under OSHA HCS 29 CFR 1910.1200, with no signal word, no GHS pictograms, and no hazard codes. SDS §3 confirms no CMIT/MIT preservative, so there is no asthmagen concern. The respirator clause in SDS §8.2.2 ("An exposure assessment may be needed to decide if a respirator is required") is conditional boilerplate with no chemistry basis; the compound carries no H335, H331, or asthmagen classification. Eye protection applies when a DA polisher is in use (pad-edge splatter is the exposure route, not chemical hazard). The water-based emulsion has VOC of 129.8 g/L (moderate; CARB compliant). A Prop 65 warning appears on the product listing, likely for trace crystalline silica in the aluminum oxide abrasive; the deduction is reflected in the health score. No PFAS.
