Achieve a smooth and uniform surface with the Norton T489 waterproof sanding sheet on paint, lacquer, and steel. The sharp P800 grit silicon carbide abrasive removes dust nibs and minor imperfections without leaving deep scratches. Designed with a durable waterproof paper backing, you can sand wet or dry to prevent the abrasive from clogging while maintaining full sheet stability. Measuring 230x280 mm, this flexible sheet easily conforms to curves and tight profiles by hand or wrapped around a sanding block. It gives you complete control when preparing bodywork and metal components for final topcoats or compound polishing.
