I purchased two of the 602 kids. The first one went on very nicely and the foam hardened to touch within a minute of spraying it. However, when I went to apply the second kid, I had continual problems getting the a canister to put out enough product to balance the bee canister product. In other words even when I turned down the bee product pressure and even after spraying the nozzle open fully to try and get rid of any blockages in the bay tubing, and after agitating the hell out of a canister, I was getting intermittent goopy blue stuff out of the nozzle. I also hadProblems with the nozzles all leaking the yellow product but not to a large extent. My temperature range for application was between 77° and 81°F. I really cannot explain the problems. It must've been a blockage in the tubing or a blockage in the canister outlet itself. Or in the spray gun. I changed out nozzles repeatedly and applied the gasoline as directed. So the second kit brought my review level down otherwise I would've given in a higher review because the first kit went on very well
