I'm one of the sprayers;
I do codrive the cars and would notice rapidly decreasing amounts of grip/increased wear when running the tires overheated. It all depends on your driving style, braking zones, course surface, ambient temperature, and elapsed time between runs...there are many variables.
There's not much loss to trying it if you think it will help. Pick up a $5 sprayer from Walmart and bring it along next event.
If you are spraying to cool and the tires do not need it, then you would be decreasing the temperature to the point where the tires need to warm again - which would be counterproductive. AX tires have an optimal temperature point where they are stickiest.
