Dura-Seal's approach is different than all other brands! We custom formulate sealers for your engine and it's individual specifications. Because of that fact, our sealers offer a 98% success rate on the first application alone...
Our sealers do not contain silicate, (water-glass) as a main ingredient and because of that simple fact, Dura-Seal® remains flexible once cured*. So, our sealer actually expands and contracts with your engine as it heats up and cools down. This allows for a repair life of up to 5 years, (when used with our Dura-Seal Extreme Additive). "All other brands use up to 100% silicate, (water-glass) in their sealers. When these other brands cure they simply crack away from the repair area... Why, because glass can't flex. Plain and simple... Dura-Seal® can!" Dura-Seal-Tech Team.
