Found this bit of info about it, and it's not all good news:

Your standard coolants become acidic over time because of the water and other additives. In theory Evans can never become acidic so you shouldn't have issues with galvanic reaction like you would with a traditional coolant over time dissolving the aluminum in the heads or radiator if the coolant isn't tested and replaced as frequently as it should.
Since this is supposed to last "forever" if I ever had to do any maintenance I would collect and re-use with any work, so I wasn't concerned with the cost since I don't ever PLAN on selling any of my vehicles, so the cost over time is way less than buying a traditional coolant, the initial "investment" is only about double that of traditional. Since this engine will not really see any track use it should not be an issue of the "over heating" problems described above. This will be a "test" for me as I was planning on using this in all my cars, one of which would my toy and see track time, if it doesn't work out, so be it and I am only out a few extra dollars.
The other benefit is that since it is propylene glycol, you can actually drink it, it is completely nontoxic and I would feel better about having my dog in the garage when I work. If she wanders in there now I am always paranoid she is going to find some ethelyne glycol and drink it.
