Review on 2 Pack Fine Grade Synthetic Clay Bar Sponge for Car Detailing - Large Size, 3x Longer Lasting Than Traditional Clay Blocks - Speed Through Clay Detailing like a Pro with the Perfect Alternative! by Rick Rogers

I used them this weekend to paint clay on my car. They worked really well, but I think real audio works better. I have already used a clay cloth on another machine and the sponge has become much better. It has almost completely removed the fine dirt that has etched into the paint, and since you can grab it it's easier to use. The clay material was quite sticky and did the job well. The side of the sponge also allows you to apply soapy water to the surface, so I no longer have to carry a spray bottle. Good product and easy to use.
