One roll of shelf liner will provide a lifetime supply of pads to improve the performance of your sanding block. I bought a 18″ x 48″ roll at a local home center for about $5. At about 3/32″ thick, I find it has just the right combination of firmness and give for finish sanding. I use spray-on contact adhesive to hold the pad in place. -Mark Thiel
