DOugster,
I got next to nowhere with my experiment also, but alot of dirt guys up here swear by it. I think there are a few steps that help to make it work
1) Have someone else buy it, it is expensive and you need ALOT, but just tell them it is cheaper than blasting.
2) Rent a ROCK drill and the compresser to drive it, again remind client that is cheaper than blasting
3) drill alot of holes along your desired fracture line as deep as possible angled per manufactures directions
4)mix it up and pour it in per manufacturers directions rembering ALOTgoes a LITTLE way
5) put a board over it and tell every one to stay away and go home for the day
6) show up the next day and inform client that their going to have to change their plans or blast afterall.
