The Scotch-Brite™ Roloc™ Bristle Disc is a moulded, abrasive filled disc for use on automotive aluminum and metal surfaces. It is an alternative to using wire brushes. The Scotch-Brite™ Roloc™ Bristle Disc is ideal for deburring, blending, finishing, polishing, cleaning as well as for coating, defect, scratch and rust removal. The non-woven, open-web, durable construction helps to resist loading and greatly increases the life of the disc.
