here is my thoughts on this one , im a machinist to trade and use water soluble oil as a coolant on machines,this oil has a rust preventer built in ,now im thinking of pouring neat cutting oil into my land rover,this will mix with the water and condensation already in the chassis box section whatever,turn it into oil(eventually the water evaporates off and just leaves oil)thus stopping the prossess,and if it runs out as its water soluble i just hose it away,any thoughts anybody??? davy
