sounds kinda risky, plus, those things don't usually get as much dirt off as you can by hand washing
but whos got the time or the equipment do a home wash? (my hose just burst) while i was washing my boat... so now i gotta duct tape the mother or buy a new hose...
i dont know much about how that Intake
deaile would work... but i dont do touchless often in any of my cars... why dont you do the powerwash place? then its easier, and detailed, and pretty cheap (we can fit out boat in those too)
