This is Recover from our pals at GunPrimer. A version of this product is part of the RASER Gate Remover Set but they were so kind as to make it available separately. The product is 2 large pieces of a cotton/polyester blend that is similar in texture to denim. It is used to treat the surface of plastic parts that need to be polished to a satin finish. Pictures are worth a thousand words, and video is better yet. Watch below.
