bm61, you are correct. I used the standard Rodeo/Cutrine/Sidekick cocktail, and that also kills sago. Maybe esshup knows something better.

I used the typical 12 volt 25 gallon rig like you see at Northern Tool. For guns, hoses, pump parts, etc., PW Mall is where I shop. Stainless steel guns are the way to go if spraying cutrine. Without proper cleaning each and every time, the aluminum guns and wands get trashed PDQ.
