IMNSHO I would never put anything like that in an engine cooling system. It will eventually clog passages in the radiator water/oil heat exchanger and other areas that have fine passages such are steam bypasses. There is NO GOOD substitute for proper maintenance or repair!

More Mouse Milk...

Since the earliest days of steam boilers, iron and steel components have developed pits and cracks (in addition to mechanical wear) due to loss of metal at the surfaces, leading to further loss and formation of deeper pits and cracks, etc

This is a electrochemical process which can not be reversed without electroplating or welding to redeposit more metal on the surface. There is no easy way to replace lost metal, believe me the boiler guys would be using it.

If an engine is far enough out of spec to leak (except English motorcycles, early Harleys and modern GM engines, which always leak) it needs serious attention not a Band-Aid!

I tend to be equally wary of extreme product claims and knee-jerk naysayers.

But curiosity drove me to Google the product. Here are a couple hits from folks who used it"

I did see Bars Leaks work long ago, but it could compromise cooling under heavy thermal loads.

SNAKE OIL!
