Re: Foam gun ?'s
I too originally bought a foam gun (hooks to your garden hose) and wasn't too impressed. I returned it and bought a foam cannon (for pressure washers) instead.
The big difference is that the foam created by the pressure washer is much thicker and dwells much longer. I tend to give the car a good rinse to remove and loose particulate then I foam one side, wash using a sheepskin mitt and rinse bucket that has a grit guard, rinse, and repeat on the other side.
For soap, I put two ounces of either Poorboy's SS&S or Optimum Car wash in the 32 oz soap container on my foam cannon and fill the rest with warm water. Some soaps don't mix too well so make sure the soap goes into solution before attaching the soap container to the foam cannon.
I've been doing it this way for years without issue and it's much faster than a traditional bucket wash.
