I use G12 cooling additive (also red) ,does everything like waterwetter, maybe even better cos it's made for all top performing german cars, and I know one guy who is a rally car driver (VW Golf Turbo) and he said that this does indeed improve cooling.
And for 1.5 L (for all your cooling need for a long time) bottle I pay 9$
Btw I use 15% of G12 and 85% destiled water (not just without minerals also without gases)
