Two questions?
Believe "Water Wetter"and "Chill Out" (similar product) were both labeled "Not recommended for use with Magnesium heads" I know Chill is so Labeled. Is Water Wetter?
Question #2, isn't there Magnesium in the CTD heads?
These products Do work well, reducing surface tension of water in coolant giving better fluid contact to hot metal surfaces. I would use one of these but heard somewhere about Magnesium in heads so have not. Anyone know for sure?
