The full read
1500 is the last cut before the buffer takes over and starts doing the talking. This is fine, deliberate work — the silicon-carbide grain removes the faint scratch pattern left by 1000 and levels what little orange-peel remains, leaving a surface uniform enough that compound has almost nothing left to argue with. Run it wet and keep it moving; at this grit the water isn't optional, it's what keeps the finish even and unmarred.
It's the setup step for a mirror, and skipping it is the usual reason a polish comes up hazy instead of deep. Mid-tier and consumable like the rest of the Wetordry line, and completely unbothered by the job — even, fine, no theatrics. Buy it to close out a wet-sanding progression before you compound; don't expect it to do anything alone. The 4.3 is the sound of a paper that leaves the surface exactly ready and gets out of the buffer's way.
Use it when
The fit is obvious.
- · Reach for the 3M Wetordry — 1500 Grit when the job is pre-compound polish, orange-peel removal, and paint leveling — 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 you already know you want the premium option; a mid-tier pick is a compromise, and you clearly are not in the mood for one.
- · Leave it on the shelf if you are flattening big panels all day — a random orbital keeps pressure even where your hand drifts.

The last cut before the buffer. Fine, even, and completely unbothered. Right before compound. The grit that removes the last scratch marks and prepares the surface to show off. In short: it earns its keep on pre-compound polish, orange-peel removal, and paint leveling.
Is 1500 the right grit lane for this?
It sits closest to 1500 grit. This is refinement territory. It improves the surface that is already close rather than rescuing a rough one.
What should you put it up against before buying?
Put it against other sheets in the same price band doing the same job — that is where speed, finish, and cost-per-use sort themselves out.
Rough start. Smooth finish. The gap between is where the work happens.
