Subject: Re: Waterless Coolant

---

Hi Alec,

I agree that Bars leaks only masks problems, though it has been good with honeycomb radiators where this is nothing more than a slight weep.

However, I feel the more interesting constituent is what I assume is soluble (i.e. cutting) oil which turns the water white. This is otherwise known as suds and is lovely stuff for machining. Has anyone else got any comments about using suds in a cooling system?
