What the crap is 'watter wetter'??
Ive never heard this before.
It has been around for a long time. I use it in my track bike. (track rule)
When I used it in my street bike, the coolant turned brown after 1 year. I don't know if that changes how it works, but if I used it in my car, I would change it every year.
