Ron are you a soap waster too?
I see the idea of having lots of suds, so there is more lubrication, more grime loosening,and less scratching.I just blast the car with the hose from top to bottom. if anything is really dirty I'll use my apc diluted, or tarminator for bad stuff before hand.
What type of pressure do the soap guns have?
I would be happy if i could get a regular hose to be a lil' more powerful?
I have a 2400 psi pressure washer but its to big for me to lug around.
