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

Works

Work well for the price, used for sanding automotive 2k clear coat. Dry sanding is easier to see the progress ,but wear out much faster than with water.

Not that good, they do not last very long, they loose there grit very fast, which slows the job, not a good value for the price,. I believe its what they are made of which is the issue.

they hold up great

nice

Excellent for the work that I normally do by hand .Now I can use my palm sander.making the easier

It just works very well.

Great for wet sanding boat gel coat. It cuts well and sets it up nicely for the next grit higher....

I had a need to polish resin and found these discs (800 - 5000 grit) did the job nicely.

They worked as expected. I use them to clean fired pottery bottoms, when needed. I havent used all of the grits, but I dont foresee any issues with them.
