I have been using the form1 casting material for over two years now. The results were lumpy to OK. I have just discovered a new product which produces a great surface result. Just follow the directions. The company is Protosolutions, J Tyler Teague is the chemist. the product is called React-Shun. His phone number is 1 844 937-7686. Ask for a sample. He’ll send you some for you to try.
Tell him Bill from Janko sent you,
