Will this stuff kill grass? I'm looking for two different products. One that will kill grass and weeds, and one that I can spot spray on the lawn that will only kill the weeds, not the grass. Does this product fit either one of those categories? One other quaetion is expiration. I have a huge jug of it and would like to use it but not sure how old it is. It is at least 4 years old. Unopened how long does this stuff stay good?
