i like a bit of snow foam, but it doesn't seem to stay on long.
i've used JWAC and that doesn't seem to stick even with a 30% mix on the bottle.
i'm now trying out valet pro2 stuff, it seems to be better, but again a 30% ratio in the foam bottle doesn't seem to last more than a couple of minutes before it runs down and thins off exposing paint to the air.
just changed pressure washer as the last one was pulsing, only a nilfisk120bar one though.
