I was having trouble with the trigger on my Piranha. As most guns with ball valves go, over time the trigger won't close by itself, and can become a real problem. So I thought I'd try lubricating the ball valve with silicone spray. I just took off the nozzle selector, sprayed down the main nozzle, and pulled the trigger a few times. And to my suprise, it actually worked! The trigger opens and closes smoothly, like new. I believe this would work with all guns that have Max-D style triggers.
Also, it works great as a lubricant for pumps, far better than vaseline. My 1500's pump is incredibly smooth and easy now, almost as if it was broken!
I really gotta get some of that...
That makes repairing triggers easier than ever. Great job!
