If you use a good HOAT antifreeze like Zerex G-05 in a 50/50 blend with distilled water you don't need any snake oil coolant additives.
Water Wetter is for race cars where the rules prohibit any proportion of ethylene glycol because if spilled it makes the track slippery and is difficult to clean up. It does reduce water's surface tension and provides a mild corrosion inhibitor package, but it is totally useless/redundant if you use the above mentioned coolant blend.

Every major auto parts store sells a water pump lubricant/cooling system anti-corrosion additive. Use the 50/50 mix and that anti-corrosion additive and that's it. You don't need Water Wetter for daily driving. As mentioned previously, it's used in racing because using Ethylene Glycol is against the rules. Makes the track surface slippery when spilled. This may not seem like a big deal when you have four wheels on the track, but picture a motorcycle hitting that stuff! Like skating on oil with water on top.
