With a 50/50 mix of antifreeze and water the friction is reduced by another 5-15 percent.

So yes, Water Wetter is not as slippery as anitfreeze, but it's a marginal improvement and if coolant is dumped where tires are being worked near their limit the car is still going off.

From the track management's standpoint, I have heard that they prefer Water Wetter because they can clean it up faster than an antifreeze dump.

And it seems there is uncertainty that these approaches are even the right answer. Water with water wetter only makes things a little less slick. This is nuts.

At least running Water-Wetter shows that I am not negligent, and responded to the issue.
