No, I have no plans on using the stuff on any of my vehicles. (Got no leaks.) But over on a motorcycle forum I frequent one of the administrators (crotchety old guy FWIW) swears by it. As in uses it on every vehicle he owns, year 'round. Swears by it. Just like those guys who preach the benefits of Marvel Mystery Oil, Lucas Octane Booster, etc.

I'm a comparatively young guy who's never had a coolant/radiator issue on any vehicle I've ever owned, so what do I know? Maybe I'm just not automotively adventurous/experienced enough. Like masraum notes, don't most anti-freezes today have corrosion inhibitors? Or does something like Bar's Leak follow the more-is-better approach to preventing rust/corrosion and overall water pumpy lubricity? Just wanted to check the PPOT consensus.
