From the manufacturer’s Safety Data Sheet, Section 8
“No H318 or H319 in SDS §2 product classification. The situational tier reflects DA/rotary machine-application splatter risk at face level · not a chemistry-driven eye hazard.”

From the manufacturer’s Safety Data Sheet, Section 8
“MIT/CMIT at 14 ppm triggers the EU allergen label statement in SDS §2.2 ('Contains'). This is trace preservative concentration below the H317 skin sensitizer threshold for product-level GHS classification. Relevant primarily for individuals with prior isothiazolinone sensitization.”

“Petroleum distillate carrier at 10·25% with no H335 respiratory irritation in SDS §2. SDS §8 notes ventilation as a precaution for the isoalkane carrier vapors in enclosed spaces · not boilerplate; the carrier concentration makes it a specific trigger. Outdoor or well-ventilated garage conditions eliminate this concern.”

TL;DR RUPES UNO Pure is a silicone-free, no-filler finishing polish confirmed to leave a genuine hologram-free finish on soft and hard clear coats · including documented use on a soft-clear Porsche with a 21mm DA. No signal word, no GHS classification; the isoalkane carrier means ventilation is worth having in a closed garage.
Apply a few drops on a foam finishing pad, two slow passes at finishing speeds, and UNO Pure wipes off cleanly. The zirconia alumina abrasive is calibrated strictly as a finishing step · it removes compound haze and light swirls without overcutting, and owners on soft paint report genuine defect removal rather than filler-masked gloss. Silicone-free from the SDS means the finish holds through an IPA wipe-down, which matters before ceramic coatings or PPF. It's highly rated on Amazon, and the professional finish-step positioning holds up in community use.
The right fit is a two-step detailer who needs a reliable finishing step after compounding · particularly on soft or sticky clear coats, or anyone prepping for PPF or a coating where silicone contamination is a concern. Skip it if you have deeper defects: community owners confirm that scratches needing a compound pass will not be resolved by UNO Pure alone.
The SDS (RUPES 9.PURE REV1 2023-04-19) carries no signal word and no product-level GHS classification. The isoalkane carrier (estimated 12·30%) contributes vapor exposure in enclosed garages; working with the door open removes that concern. A biocidal preservative (MIT/CMIT) at 14 ppm triggers the EU allergen label statement for pre-sensitized individuals only. No Prop 65. Leave-on product · residue wipes to microfiber, not to drain.
Yes. SDS §3 (RUPES 9.PURE REV1 2023-04-19) lists no dimethicone, cyclomethicone, D4, D5, D6 (cyclopentasiloxane), polydimethylsiloxane, or any silicone compound. The product is safe for use before paint protection film, ceramic coatings, and paint-prep work where silicone contamination is a concern.
Zirconia alumina, confirmed in the Amazon product specification. Zirconia alumina is a harder, more durable abrasive than traditional aluminum oxide · it cuts consistently across soft and hard clear coats without fracturing prematurely. The diminishing-abrasive behavior means the cut level drops as the pad works the polish, leaving a refined finish.
It is designed as an ultra-finishing step after compounding, not as a standalone compound replacement. Community evidence confirms it removes compound haze and light swirls, including on soft clear coats. For scratches deeper than 2000-grit equivalents, start with RUPES UNO Protect (compound) or a coarser correction product · owners report exactly this when it didn't resolve a deeper problem area.
RUPES documents it for use with their BigFoot DA polishers across pad types. Community confirms use with a white foam finishing pad on a 21mm-throw DA at standard finishing speeds (4,500·6,000 OPM). The brand's design goal is pad versatility · performance should be consistent across major foam finishing pad ecosystems, not just RUPES pads.
No. The Rainforest data for ASIN B085TM59NG (fetched 2026-05-29) shows proposition_65_warning: false. This is consistent with the EU REACH SDS, which does not flag Prop 65-specific chemical classifications.
