I bought these to grind Bondo on a 3D printed PLA for a suit armor I was building. At first I applied Bondo quite thickly and then sanded it smooth with different grits. It worked well but I wasn't impressed with the smoothness. I then tried wet sanding with these sponges and it gave me much faster, better results and much less wear on the sandpaper. So I highly recommend buying these and spraying the surface to be sanded with some warm soapy water to help!
