Poor advice sent wrong substance
I went as far as to send a sample of the texture of rubber I needed and they advised me to order Flex 50 and it's not even close to the feel of material I sent them. Now I'm stuck with 2 gallons of product I have no use for and out of a lot of money and you ask me how I taste this item.
