Anyone know where to find RMI-25?


Nov 2, 2003
Some of you guys might remember this stuff for cooling systems being sold long ago. Anyone know where I could buy some these days? I've tried Home Depot, Target, Wally World, Pep Boys, Auto Zone, Checker Schuck's Kragen, Advanced Auto Parts, and even Sears, and still no dice. I've seen it online but I don't trust online places. Any help would be appreciated, I want to try this stuff.
