3M™ Wetordry™ 401Q is a premium waterproof abrasive sheet constructed with ultra-sharp silicon carbide mineral particles bonded onto a durable, waterproof paper backing. Engineered for precision performance, the silicon carbide abrasive cuts faster and leaves a smoother, more consistent scratch pattern than conventional aluminum oxide sheets. Designed for both **wet and dry sanding**, it can be used by hand or with sanding blocks and mini orbital sanders. It is the ideal choice for fine paint defect removal, color sanding, and pre-polishing preparation.
