Probably the same as Bars Leak. And yes, only try it as last resort. Also, when you do get a new motor or the problem solved for good, plan on getting your radiator worked on, and if its a plastic radiator, its likely disposable and you'd just have to buy a new radiator. The stuff does have a chance of working, but it clogs up lots of other stuff too.

The general rule of thumb is one application is ok, but any more than that is going to cause problems. Personally, I would only use it to get a vehicle sold but not in something I plan to keep.

I see a lot of posts in a forum search on this topic saying this **** works. Lifetime guarantee. Works with antifreeze.

Anything on the market that will seal a busted gasket will more than likely seal up other small coolant passages as well, like a heater core for instance. Remember, if it sounds too good to be true...
