Obviously, a glycol/water combination with water pump lubricant and aditives will corrode less and cool better than water alone.
I do not dispute that water wetter is useless with normal mixtures, but it would be useful to know why.
Water wetter, of course, does not say that it is useless to what must be most of the people most of the time, I imagine for obvious reasons.

Commercial anti-freeze mixed with water has everything needed to prevent corrosion and protect the water pump seal. Like motor oils, you do not need supplemental additives when you use a proper concentration of antifreeze and water.
I've never been able to figure out exactly what is in Water Wetter, but there's a chance that it may have some incompatibilities with some antifreeze additives.
It's probably a good idea to use it in a race car that uses straight water as a coolant, but I do not recommend it if you use a proper antifreeze and water blend for the above reasons.
