Having "blown" a few hoses over the years, and like I said, having been burned by overheated/pressurized systems this is the biggest issue for me. Way less "stress" on the entire system with low or no pressure. Minor head gasket leaks may not be a problem with this stuff, should you encounter one. Way less likely for a loose hose clamp to become an issue. Stuff happens out there, even when you take the best precautions, I see this as additional "insurance" to protect my cooling system/engine. For those with alloy heads, this stuff may save your butt from warping one!

How about, "Fix it before it breaks!"
