RMI-25 coolant system treatment

I just read an interesting thread (on another site) about RMI-25. It is a coolant system cleaner/conditioner, that seems to act
similarly to the way Auto RX does in the crankcase. I was thinking that after 80,000 miles, my Ranger's system could probably use a cleaning. I was wondering if any of you had ever heard of it, or used it. Give it a read, it sounds like a pretty good product...
