I read an article about this waterless coolant, which sounded like a much better than the tried and true regular ethyl glycol anti freeze.

Has anyone used this, and what are your opinions. I have a clean rebuild I am finishing (455) so this would be the time to introduce it. According to the article, it cools better, has higher boil temp and lower freeze temp and doesn't deteriorate or need replacing nearly as often, and is better at protecting from corrosion.

If all that is true, the only downside I can see would be someone adding conventional coolant at an oil change, or needing to add on the road if a leak develops. I have not had any overheating issues in the past, but regular requires replacing every 2-5 years as regular maintenance.
