Frequent Questions & Answers
Question: So, what's the big difference between Dura-Seal® and all the other brands?
Answer: Dura-Seal® is better because we don't use water-glass (sodium Silicate) as a main ingredient! Water-glass actually turns to glass onced cured in your engine and simply cracks away from aluminum cylinder heads and blocks. Dura-Seal® doesn't crack away. Our formulas are actually custom mixed for your particular engine's temperature the day your order it so it's fresh and strong when you go to use it. And because it's formulated for your individual engine's temperature at the head area, it won't cure in other areas like radiators or heater cores. It's a better more advanced product for todays vehicles.
Question: I've seen other products that advertise they can work in engines, radiators and heads...
Answer: There is no such thing as a one-stop-sealer! each Dura-Seal® product has been specially formulated to repair each individual problem area and work within their temperature ranges.
Example, our Dura-Seal® Radiator Stop Leak cures at a lower temperature then our Dura-Seal® Block Sealer, which requires a higher curing temperature. Our Dura-Seal® Head Gasket Sealer cures at an even higher temperature.
Question: What's in Dura-Seal® and what does it do?
Answer: Dura-Seal® combines the best chemicals, organic and inorganic compounds at trade-secret amounts to produce a product which has the strength of steel yet maintains the flexibility of polyglycol polymers and offers the hard-as-diamond durability of hectorite mineral with the flexibility of organic fillers.
Question: Can Dura-Seal® damage my engine?
Answer: Dura-Seal® sealers cannot hurt you engine or void your vehicles warranty. The ingredients in our products or formulated to work through the cooling system, not cure there or plug them up like other brands out there.

Question: I've read that Blu_e Deviel, Thermaa Gaskit, IroinTiet, Barz, Steal Seel and all other brands use Sodium Silicate, (water-glass) in their products, is that the stuff that turns to glass?
Answer: That's right, Sodium Silicate, (water-glass) turns to glass when cured! Glass can't expand or contract, so it simply cracks away from the area it's trying to repair. Also, water-glass IS NOT COMPATIBLE WITH ANTIFREEZE. That's two reasons Dura-Seal® does not use Sodium Silicate as our main ingredient. That means our sealer actually stays flexible onced cured and can last for years...
