Why Chemical Repair Has Earned a Bad Reputation

Some head gaskets cannot be repaired if the damage is too severe.

Promises of a 99% success rate, money-back guarantees, experienced technical support, proprietary formulas, nanotechnology, pour and go, only one capable of repairing aluminum heads etc. these claims have proven to be substantially bogus.

A prominent brand claims it mixes a custom formula for each specific vehicle due to the different operating temperatures. This is hype, as over 95% of all gas car & truck’s operating temperatures are between 190f to 210f. Also their formulas uses “polymers” or “flexepoxy” – terms that sound very scientific but are only catchy marketing phrases.

Any company that claims that there is no sodium silicate (water glass) in their formula is not telling the truth. It may not be the main ingredient, but there is some in the formula.

Some mechanics will say, it’s just temporary – a Band-Aid – it won’t last – it will clog up the cooling system and mess up the whole engine. This is NOT TRUE, and definitely not true if done properly.

In the field we have encountered every solution available online and in auto parts stores. When a customer tries a different product and it fails, they call us, ours works.

We supply hundreds of repair shops all over the United States who believe this the best head gasket sealer on the market. Call or e-mail for referrals in your area.
