If i was running traditional coolant again, I would give this stuff a try RMI-25 Protects Your Engine (rmi25.com)

Lots of good long term reviews on line.

The biggest issue for me was corrosion. Before Evans, I ran Valvoline maxlife coolant on a fresh rebuild and I could not believe the hard white build up on my brand new water necks about a month later. Not sure what that was ?

Did you use distilled water or tap water?

I phoned the coolant manufacturer and deionized water was recommended and used.
