Simply Auto WD1000 Wet and Dry Paper, 1000 Grit, Pack of 25What is 1000 grit sandpaper best for?Work that happens while the job is still going on. A thousand grit is the grade for de-nibbing between coats: taking out the dust speck, the insect or the bit of grit that has landed in a fresh coat, so the next one goes on over a flat surface instead of over a lump. It will also knock a run or a sag back level, which lets a panel be recoated rather than stripped and started again. Away from paint it prepares chrome, stainless and alloy for polishing, which is why it makes for a good choice on home and industrial restoration work as much as bodywork.Timing matters when de-nibbing. Let the coat harden properly first, since sanding paint that is still soft drags rather than cuts and leaves a mark worse than the one you started with. Then work wet, lightly, and only over the defect itself: the aim is to level that one spot, not to flat the whole panel.Twenty five 23 x 28cm sheets to a pack. Silicon carbide grit, electro coated so it does not shed or crumble in use, on a resin bonded waterproof backing that stays flexible and folds around a block or a curved panel without cracking. It is a full standard sheet, so it cuts in half for a half sheet sander or into thirds for a third sheet sander when working dry. By hand it can be used dry, or wet with water, oil or lacquer to keep the dust down and stop the sheet clogging.
