Thought I would share the response I got from Evans coolant after
showing them a photo of typical Vanagon water jacket seal corrosion, and
asking if using their coolant would help:

".......we have seen this type of corrosion in steel head as well as
aluminum. The culprit is actually the acids that form over time due to
the electrolysis. Our coolant will eliminate all the corrosion factors
along with the electrolysis. Our coolant is also phosphate free."
