They say that wet or dry polishing is fine, but it is better to polish wet.
This is how I used these to wet sand the bottoms of my pottery to make them look nice and smooth. How easy they are to use makes me love them, but I didn’t like how the diamond circles fell off. The 200 and 400 were used about the same amount, but the 400 lost a lot of sanding circles because it was used less. This was the first time I used them. To be fair, I sanded about 40 pots with them. Find something that works better for this.
3 stars: I changed my rating from 1 star to 3 stars after I read this. The company called me, refunded my money, and told me to buy the new design. This is a much better idea than the old one, because I didn’t lose any of the parts that I used to sand. However, I used them only once. See how well they work when I do more sanding so I can figure out how well they work.
