These Faithfull Wet & Dry Sanding Sheets are ready cut to wrap around a cork block, such as FAIC18. They are made from a flexible, latex impregnated waterproof backing paper that is then coated with abrasive. Use wet or dry for sanding paint, primer and body filler. Coarser grades are ideal for removing major imperfections. Finer grades achieve a very fine finish for final painting. Super fine grades allow exceptionally fine finishes to be achieved especially when used wet. Specification: Size: 115 x 140mm Grade: 2 of each grit - P180, P240, P320, P500, P800 Pack Quantity: 10
