Dura-Seal is the only available liquid head gasket sealer which does not use "water-glass" as a main ingredient! Since we here at Dura-Seal don't use "water-glass" our Dura-Seal Head Gasket Sealer actually stays flexible and because of that flexibility you can use our Dura-Seal with any engine that has aluminum heads or blocks (like Cadillac Northstar, Subaru, BMW, Mercedes, Audi, etc). Also, since our sealer stays flexible and cannot crack-off, most customers get over 4 years of repair life.

Why didn't the last sealer you tried work on your engine's head gasket?
BARZ, BLU_E DEVIL, STEAL SEEL, THERMOOGAZKET, NANO TECH, K-n-W, AND ALL OTHERS BRANDS ARE NOTHING BUT WATER-GLASS!!! *actual names of certain brands have been altered... Water-glass based sealers like these listed above have been around since the 50's when all engines were made of steel, these old fashion sealers can't flex, they can't expand and they can't contract with the engine metals.
Most vehicle engines now-a-days have aluminum cylinders heads and many even have aluminum engine blocks. All Cadillac, Subaru, Volvo, Mercedes, and BMW engines are entirely aluminum and expand about 33% more than the old steel engines during heat-up and cool-down. Those old fashion "water-glass" sealers can't flex with the new aluminum engines and simply crack-off. BARZ, BLU_E DEVIL, STEAL SEEL, THERMOOGAZKET, NANO TECH, K-n-W, AND ALL OTHERS BRANDS are simply outdated critically flawed sealers which shouldn't even be on the store shelves anymore.
Did you know only Dura-Seal makes custom individual formulas for every vehicle out there? That means, we offer different formulas for different engines. Why would we invest the time to do that? It's simple, to make a better sealer we needed to have the highest success rate in the industry. In order to do that, we had to make each of our engine specific formulas cure at the exact temperature of the head gasket area of each engine, (Example: a Toyota 4Cyl. engine has a temperature range of about 295 to 320 at the cylinder's head gasket area, a Porsche 911 6Cyl. has a temperature range of about 325 to 370 at the cylinder's head gasket area).
By customizing the curing temperature of each of our sealer kits, we can assure you that our sealer will only bond and adhere to the cylinder's head gasket area of your engine. Our Dura-Seal simply can't cure in a radiator or heater-core, it's just not hot enough there. So Dura-Seal cannot clog or gum-up other areas of your system, it can only cure at the head area based on your engines specific temperature range. That's science...
The other brands like: BARZ, BLU_E DEVIL, STEAL SEEL, THERMOOGAZKET, NANO TECH, K-n-W, AND ALL OTHERS BRANDS which use water-glass all cure at the same temperature, exactly 210 degrees. That's the scientific curing point of water-glass! So that means if you use their water-glass based sealers it would cure in your radiator, heater-core, hoses, even the water pump because these areas can heat-up beyond 210 at any time while the enigne is running. Not only that, but, if they all cure at the same temperature, how is any one of those other sealers any better than the other. Water-glass sealers are just not very smart... Dura-Seal is simply better science, better technology and yields better results...
