The reason that surfactants may be beneficial in the automotive cooling arena is because that they help reduce the localize boiling that may occur in a typical engine, especially the cylinder heads.

The benefits can vary wildly in production engines, because the manufacturing process can leave things like flashing and casting inconsistantcies that can cause more localized boiling in one engine over another engine, even though both came off the same assembly line.

What you have to ask yourself is if you believe that your system reaches the temperatures to cause boiling in the waterblock (I hope yours does not!).

On the other hand, using water wetter to combat system corrosion is a diffferent story, but Redline offers no guidelines as to the change interval (if there is one), so I am unsure of how long it will offer protection.

One thing is for sure, if you can use water wetter instead of antifreeze for corrosion protection, you will be more efficient in moving the heat loads to the radiator, due to the lower concentration of wetter needed compared to the amount of antifreeze.
