Don't know what system you're using Leo, but most operators that use high pressure application and hydrominders don't run near the required concentration. They look on the container, and it recommends a certain concentration. Then that's what they put in their hydrominder, overlooking that this solution again mixes again with a water stream and is diluted another 90%, if not more. I have a water wizard, which is mixed and then allowed to be drawn into the high pressure pump. I have to use big tips usually somewhere in the red range to get adequate water breaking on the car. The same product works great with a purple tip in a low pressure application.
HP wax is not the best way to apply the product. There is a lot of waste due to purge times both before and after the CCP cycle. Still, my HP CCP costs about .10 per car, which is reasonable enough for me because it breaks well and leaves a residual water repellent effect that customers comment about. .The same product in a low pressure would probably cut that product cost in half, (or even more when considering water usage).
