I bought this brand becauaw of the giod reputation of U S Art Supply. I specifically wanted it to finish off my Sculpey clay pieces I was making into wall hangings and jewelry, among other things. I ran into trouble with a some pieces, but it seems the clay was too wet. Using it now on other pieces, I'm getting a beautiful, shiny finish. I find it difficult to apply as my brush gets dry quickly, but I change it often. It's worth it to get the finish once it dries. I do recommend this product. The C. S. department is very helpful with questions as well.
