6 Inch (150mm) 3000 Grit High Performance Waterproof Hook & Loop Sanding Discs Heavy Duty Silicon Carbide Round Flocking Sandpaper for Wet/Dry Sanding Grinder Polishing Accessories, 20-Pack

Not quite as good as 3m but the quality for the money is good.

Ive only used a couple of these so far, but Im happy with em.

They are only good for wet sanding...

have not used wet sanding disc before but them seem to wear out very quickly. I was wet sanding gelcoat on a boat and was only able to cover about 4 square feet with one disc. This may be due to the hardness of gel coat varies standard paint and body work on a car.

This product worked well on an orbital sander for dry and wet sanding. I used it for removing oxidized gloss coating on Pontiac G6; stripped off damaged gloss coat without damaging the original paint underneath. Reapplied gloss coating, and used the 2000 grit sand paper to buff out the expected imperfections of the high gloss sprayed on by way of rattle can method. Very pleased.

They were of excellent quality and about 1/10 the price of 3M

Best disks Ive ever used. They just keep working and working. No tear outs or lifting. Just great disks. Im running 2K 5K and 10K and then just a quick polish with a buffer and it looks like glass. Seriously great disks.

Typically use 3M but the price made me curious. Pretty good stuff for the price. Used it wet so it lasted a decent length of time. Would buy again.

they r good

Got the job done
