Actually works; unlike other comparable products.

When dealing with additives, it's hard to tell who is selling snake oil, who isn't, and exactly which product actually works for the problem you have since some will pretend to fix things they don't by using specific wordings, etc.Well, this stuff definitely works for head gasket issues. Whether or not we're talking a true permanent seal is up for debate, but it for sure did the job. I don't see any more steam, and I'm not burning water or oil anymore. So I can say with some authority after trying this on 2 different vehicles that this actually does work. It's not "instant" and took a couple of days of normal driving, but it fixed the issue with all leaks in the radiator, heater core and head gasket between the 2 vehicles.It's night and day between this and K-Seal which basically did nothing but make the problem worse for me on my Bronco and the 2nd attempt on a Ranger didn't fix anything either. K-Seal advertises head gasket permanent fixes but them int he small writing under the flap goes on to explain it only fixes EXTERNAL head gasket issues and only other leaks that occur on the outside (meaning the leak is leaking outward), yet 90% of head gasket issues are internal. K-Seal also gummed up my thermostat; just be aware of what each product does and what you're trying to fix. I'm sure K-Seal might fix specific issues, but it didn't fix any of MY specific issues, even though they put it on the label that it fixes certain things.Bottom line; this does what it says.

Was my go to when head was finished.

Maybe I'm just over cautious.

Great

I used this on a Honda with a crack head . Guy live in Dallas, Tx was trying to make it home. He had a blow head gasket, he contacted me 8 day later said the car was still going strong. Heck that surprised me
