The full read
This pack lives in the middle of the story — the grits between the coarse work and the reveal. Spanning 600 to 1500 in silicon carbide, it covers the whole in-between stretch of a finishing job: knocking down primer, smoothing between lacquer or clear coats, and setting a surface up for the pre-polish stage. Silicon carbide is the sharp, brittle grain that fractures to fresh edges as it wears, which is exactly what you want cutting fine and cutting clean.
The wet-or-dry part is the quiet convenience. Run these dry for quick knockdowns or, better, run them wet — the water floats away swarf, keeps the paper from clogging, and leaves a finer, more even scratch that finishes closer to a shine. Having 600 through 1500 together in one sleeve means the right grit is always in the drawer instead of the one you're missing. Mid-tier price, unfussy, and the kind of assortment you quietly restock without thinking about it.
Use it when
The fit is obvious.
- · Reach for the 3M Wetordry 600–1500 Pack when the job is auto primer, between lacquer coats, and pre-polish — 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 if the work is edges, profiles, and tiny repairs — those are easier to control by hand.
