Contact the State of Washington and ask them where they get theirs. They have 
regulations on the quality of sealant they find satisfactory (in this 
instance, for sealing drill-hole casings), so they must have a list of

somewhere.

The trouble with the Web is its information overload. It has been said that 
getting info from it is like drinking from a fire hose. I hope this tiny 
sampling is helpful.
