I can compensate you for your time, and wouldn't need more than 2 or 3 hours. Before I buy one I wanted to time out some dilutions to make sure I can get an 8:1 ratio.
i got one. I'm in pasadena on the weekends. I need it for a detail tomorrow but you are welcome to try it out on sunday at my place in pasadena. Its the cam spray one with karcher adapters.
