Thanks Ed for the link,I didn't read nothing about their chemicals but the foam nozzel looks just like the one I've had for 10 or so years.
I know they make special chemicals for foam but never how tried any of them,I've only tried with what soaps I already had.Plus I thought you needed to apply air to the system to get the real foam thats needed.The soaps I tried though the foam nozzel foamed a little but not much even with hotwater,was not to my liking.
At the time I was running 12v systems with no room for added eqt.(air),I now run 115v system and haven't yet looked into whether are not the gen will handle the extra load in runnning a air system.I don't brush anyway but would like to atleast apply the wax though a foam system which in my thinking I would get a cleaner and faster rinse job,rinsing takes longer to do then washing.
The foam has still been in the back of my mind after buying the 115v system but haven't fallowed though with it b/c of the time factor it take me to stop and change nozzels,I run a open gun.I don't need to get to thinking about it again but would still love to try a true foam system.I think it would look pretty neat apply maybe a blue/red/green wash foam fallowed by a bubble gum/pink/yellow wax...I think foam would make a geat 2 step wash job.
