Just remember. No Bentonite dealer will guarantee the stuff. It worked for Cecil. It didn't for me and I have tried it twice. If you don't get 110% coverage, you are in trouble. I'm sure there must be some more success stories or they couldn't sell the stuff. Has anybody else gotten positive results?

If there is any oil well drilling around your area, there will be Bentonite for sale. Look for oil field drilling suppliers. I think I paid seven bucks plus change for 100 pound bags.
