Sounds excellent ( Evans Waterless Coolant)...
Evans Waterless Engine Coolants
I was keen, after checking out all of the info...and I went to buy it last week.
With the Prep fluid/ flush X 4 bottles, plus the coolant X 4 Bottles required....it was going to cost me around $700-00 !!!!
Opted for "Water wetter" instead,
Red Line Synthetic Oil - WaterWetter® Coolant Additives
