I have a foam cannon too and it is pretty cool. I have a question about the pressure washer though. I just have a gas one that is like 3100 psi or something but used it a couple times with the foam cannon. What PSI is your pressure washer I like the idea of spraying it beforehand to get all of the dirt off, but I am afraid to do it with this strong one. Is it a good idea to invest in an electric pressure washer around 2000 psi for washing cars with? Also, after you spray it with the foam cannon, do you rinse it off after a few minutes or do you just start using the 2 bucket method with the foam still slowly dripping down?
