Anyone has coolant over flows at the track?

1% evil, 99% hot gas.

Neither SCCA nor NASA require straight water in their race cars. They are the largest amateur race sanctioning bodies in the US. NASA specifically prohibits ethylene glycol but says nothing about propylene glycol (Evans). Neither they nor any other body I know of prohibits any kind of coolant for their HPDE (non-competition) events.
Now, I know the pro racing organizations all prohibit ethylene glycol, but I don't know that they all require straight water.

Coolant overflow - I saw a little coolant dried around the catch can once, then again another time, then again, then the engine got replaced. I don't think it's good or normal. The catch can is so that doesn't 'normally' happen.

Ethylene Glycol-based antifreeze and other additives that may cause a slippery condition if spilled on track are prohibited.
SCCA says:
Glycol-based coolants are not permitted. Additionally, any other coolants that significantly reduce the friction properties of the track beyond what plain water does are not permitted.SCCA says:
I suppose if Evans is not "slippery" it might be allowed by NASA. However SCCA just says "Glycol-based" which I think would include Evans. Does it cause a slick surface or is it just like water? I have no direct experience. If in fact Evans is not "slippery" it might be an interesting option for NASA races.

2010 SCCA Pro Racing Regulation 2.7.4.4 (This is the World Challenge regulation but all the other pro series rules say the exact same thing, MX-5 cup, etc...)

Of course this is SCCA Pro Racing Regulation - perhaps Club Racing or Autocross has less strict requirements.
But I guess what really matters is if Evans is slippery like traditional coolant if spilled on a track? Anyone know?
