Wet & Dry Sandpaper

Wet and dry sandpaper is a waterproof abrasive sheet for hand sanding paint, clear coat, filler, plastic and metal. Used with water, it cuts evenly, runs cooler and clogs less. The range is Colad waterproof sanding sheets, sold singly in 1000, 1500, 2000 and 3000 grit.

How to choose

• Grit: 1000 and 1500 take down dust nibs, runs and filler, while 2000 and 3000 refine those marks so a compound can polish them out.
• Work up through the grits rather than jumping from 1000 to a compound: each finer sheet removes the scratches of the one before.
• Hand or machine: the sheets wrap round a sanding block for single nibs and small areas. For whole panels see Wet Sanding Discs.

Good to know

• Keep the sheet and the panel wet with clean water, and rinse the sheet often.
• Sanding removes clear coat for good. Mask edges and body lines, where paint is thinnest, with Masking Tapes, then take out the sanding haze with a compound from Heavy Cut Compounds.

What grit sandpaper removes car scratches?

Go no coarser than the defect needs: 1000 or 1500 grit levels a deep mark, run or nib, then 2000 and 3000 refine the sanding marks so a compound can polish them out. Light scratches and swirls need no sanding at all, only a compound.
