The full read
At 2000 grit you are barely removing material at all — you're persuading it. 3M Wetordry is silicon carbide on a waterproof backing, and it's built for the slow, wet, unhurried work of taking an automotive clear coat or a polished finish from 'nearly there' to genuinely flawless. Run it dry and you'll gum it up; the water is not optional, and neither is the patience.
The reason it goes on wet is craft, not theater: the water floats away the removed material and keeps the fine grain from clogging, so each pass keeps cutting evenly instead of loading up and scratching. Silicon carbide is the right grain for clear coat and paint because it's hard and it stays sharp through the slurry. Done right, it leaves a surface so uniform that the polishing wheel afterward has almost nothing left to argue with.
This is a specialist's sheet, and pro tier for good reason. Auto detailers, paint-correction people, and anyone chasing a mirror on lacquer will get exactly what they came for. If you're sanding a deck, this is the wrong end of the drawer entirely — 2000 grit will only frustrate you on anything that isn't already close to perfect.
Use it when
The fit is obvious.
- · Reach for the 3M Wetordry — 2000 Grit when the job is auto clear coat, polishing, and wet sanding — that is the fight it was built for.
- · Silicon carbide bites sharp and fast, and it loves water. Brittle, brilliant, a little reckless — the grain that leaves glass when you keep it wet.
- · This is refinement territory. It flatters a surface that is already close; it will not rescue a rough one.
Skip it when
The job asks for something else.
- · Leave it if you still need to remove stock, paint, filler, or machine marks; fine grit only polishes over problems it cannot fix.
- · Leave it if the budget is tight enough that value-per-pack matters more than top-end feel and longevity — good mid-tier paper will get you there slower.
- · Leave it on the shelf if you are flattening big panels all day — a random orbital keeps pressure even where your hand drifts.
