Has anyone tried using Evans NPG coolant? You don't mix water with it and it
doesn't boil until 370F. Evans recommends 0-7 psi cap since engine hotspots
won't cause local boiling. They claim no oxidation or corrosion for metal
parts, and histories of hundreds of thousands of miles in trucks.

Just wondering if anyone has positive or negative experience with it.

Ken Welter is running it now and so far so good. However he is not measuring
the temp down near the base of the spark plug so who knows. Unless we start
doing that we will never really know what is going on in our engines cooling
wise. The metal temps are the very bottom line.
The water temp can be anything but who knows what the metal temperature is.
