Don't use water wetter and take your bike down to VIR in the back of a pickup truck. It COULD get down to freezing levels again, and the added windchill over the radiator as you drive at 70mph could freeze the water in the radiator and burst it.
If you want to use water-wetter, change the coolant down there.
When they say no glycol-based coolants, they mean ethylene-glycol (slippy stuff), no propylene-glycol (non slippy)
