The Triangular Wooster AeroSander™ is able to cover large areas and reach into corners. The new AeroSander 220-grit sandpaper achieves 30 percent faster results and has improved clog resistance. The sandpaper has extra-fine grain, perfect for sanding between coats or final surface sanding prior to painting. Coarse-grained 80 grit and fine-grained 120 grit triangular sandpapers are also available. All AeroSander items utilize a strong hook-and-loop fastener system to prevent the paper from tearing and curling and allow for quick paper changes.
