These abrasive products may be used for either wet or dry sanding applications, which allows you to switch between both methods with one sandpaper. Wet sanding and dry sanding each have their own advantages. Dry sanding saves you from having to dry the surface to check the progress of your work. Wet sanding works more quickly, holds down the dust and reduces clogging of the sandpaper. The flexible backing of this abrasive is perfect for sanding and finishing plastics, metal, body fillers, glaze, primer and clear coat with a more consistent scratch pattern. 3M Wetordry Sandpaper has long been a great choice for auto repair jobs – there’s no need to spend extra time switching sandpaper between wet sanding and dry sanding.
