Steve...I truly don't know what others experience with WW is when they say it doesn't work or why you think it's bogus, but SCCA autocrossers by the thousands have used it for many years to keep coolant off the courses. I can think of nothing more brutal on a cooling system than autocrossing...full bore 1 to 2 minute runs followed by several minutes of idling (especially in Pro Solo), mostly during hot summer months.
But hey...you've got a perceived problem that you're trying to resolve, and I hope you and your cooling system find inner peace.
