I bought a gallon of Roundup that had a trigger type spray nozzle. The plastic piston with an o-ring on it will return very slow after the trigger is pulled. I sprayed it with silicone lube but it didn't make any difference. I don't know if it will return faster once the temperature goes up or not. It was about 65 this morning and still returning real slow. I couldn't see any way to take it apart and increase the clearance.
Those trigger type nozzles that come with various spray are really junk. I have a 2-gallon garden sprayer that I pump up, but I can't close the nozzle enough to just let out a little Roundup; it will pump out a gallon quite fast.
