All, I have used Speedzone the last two years without great results. I know to put some saop in to break down the surface tension to help efficacy. I've never had much success with it. I don't think I was using it correctly. I was putting in about 3 to 4 drops of dishsoap in a 2 gallon mix. I recently talk to an experienced veteran (chemical guy), he says to use a "sticker". Please advise on the use of a "sticker" (name and quantity, assume I'm mixing up a 2 gallon batch at a time) or is soap good enough.
