Water wetter's effect on coolant/water is less (far less) than on pure water.

I have had much the same experience when I was having cooling problems both
with Water Wetter and its competitors (eg Hyperkuhl). And of course if the
system is working properly then the coolant temperature is controlled by the
thermostat, so no additive can have any effect except to make the thermostat
run slightly more or less open.
If you dig into the data presented by Redline, it quickly becomes clear that
the main advantage comes when you use WW plus pure water, instead of a
water/antifreeze mixture. I can vouch that pure water cools measurably
better than water/antifreeze, but the difference is not large and only
appears under specific circumstances.
My opinion, it does work as advertised. But having better heat transfer
between coolant and radiator will only help if that is the limiting factor.
In general, I feel our radiators are big enough, and that heat transfer is
limited primarily by water and/or air flow. The only time this would not
apply is if you have increased engine output substantially, and are running
the engine at full output for long periods of time (eg racing).
YMMV, etc.
