 right so when i mentioned that it penetrates the metal so if you picture it in your head and you think of a dry slate and then you drop some water say even a paper towel is a good analogy if you put a drop on a paper towel it spreads right out and you can kind of see it penetrating and then our product is going to continue to do that so it can continue working continue creeping throughout and then it can you know get anywhere at that point
