I use these pads for wet sanding painted surfaces. They include 3200, 3600, 4000, 6000, 8000, and 12000 grit sanding pads. They make a great painted surface. The shine you get after properly wet sanding is amazing. I use them with Createx Auto Air paints. I coat with 3 coats of the base color. Then I do a complete series of wet sanding with the pads. and you could leave the paints like this if you want a satin finish, but I usually coat with 3 to 5 coats of alclad II clear gloss Lacquer. Then I lightly wet sand with the 4000, 6000, 8000 and 12000 grit pads. And then finsh off with Novus 2 and then Novus 1. You can see your face in the finish. These pads are absolutely wonderful.
