Query: not what i thought

I thought this product would stop a stump from a tree I had to cut down from bleeding. I bought 3 cans and they didn't even begin to cover the stump, next time I ordered 4. Well the bleeding eventual stopped on its own and now I have little green sprigs growing out the side of the tree. I thought this would stop all growth. Dont waste your money. Plus, half through spraying all of the cans stop working with liquid left in there. What a wast of time and money.
