Automotive Wet Sanding
This 3M Imperial Wetordry sheet is built for wet sanding old paint, primer, sealers, lacquers and final coats. It serves automotive refinishers and detailers who need a flexible abrasive for fine featheredging or the last sanding step before priming. The paper works on plastic and painted surfaces alike.
1500 Grit Finish
The single specification that decides fit is the 1500 grit rating, which targets ultra-fine surface preparation rather than heavy material removal. It is not for buyers who want aggressive stock removal or coarse shaping of body filler.
Flexible Backing Integration
The flexible backing conforms to curves and contours without needing a rigid sanding block, freeing up hand pressure for consistent contact on complex panels. It requires water or lubricant for wet use and pairs with standard hand-sanding workflows.

Questions about this item
How does 1500 grit perform when sanding a final clear coat by hand?
1500 grit removes orange peel and minor runs on clear coat without cutting through, leaving a uniform scratch pattern that polishes out quickly.
Can the Imperial Wetordry sheets be used with a dual-action sander or only by hand?
The flexible backing conforms to contours for hand sanding; it is not designed for machine hook-and-loop pads.
What backing size do I need to cut the 3-2/3' x 9' sheet to fit a standard sanding block?
Trim the sheet to the block dimensions — typically 2-3/4 x 5 inches — using the full 9-inch length for multiple wraps.
