How to apply anti static spray??

We have a few competitions coming up that have announced they will use static guard. We have bought a spray bottle of the “Heavy Duty Staticide” #2005. We were wondering if anyone knows if Vex has any guidelines of how to apply the anti static, or how heavy they recommend applying? We have noticed in competition that there is a varying range of how much is applied. Sometimes the fields are very sticky, and sometimes we can barely tell that anything has been applied. Any advice would be greatly appreciated.

VEX made a video on it. Just spray it on the field a couple squirts each tile I think.
