## Description

Suddenly noticing your temperature gauge spring towards the high end is not the best way to start your day. School, work, errands — your daily routine should not be compromised due to head gasket problems. When you experience this problem, you probably think about the time and money that will be spent in search of a block seal solution. But there’s good news: a cracked head sealant doesn’t have to be expensive or time-consuming. Our Bar’s Leaks Head Gasket Repair is scientifically formulated to permanently seal coolant leaks that are the cause of most overheating problems. It’s easy to apply, and it’s available at only a fraction of the cost of getting the same block seal fix from a mechanic. How does the need for cracked head sealant come up in the first place? Usually by overheating, which can be caused by a blown head gasket, cracked head or a leaking block. Bar’s Leaks Head Gasket Repair eliminates this problem — . This product contains a blend of aramid and refractory fibers, which provide the strength of a bulletproof vest and the heat resistance of fireproof clothing. As these particles penetrate a crack or the blown head gasket area, they lock together and bond, forming a hard, permanent ceramic-type seal. At Bar’s Leaks, we employ a team of top-flight chemical engineers who specialize in solutions such as these. Each product, our cracked head sealant included, is custom-designed to be effective, affordable and easy to install. You don’t need any special automotive expertise — you just need to be able to pop and lift your hood. The rest is about as simple as any car maintenance can be. Forget that repair bill. Simply use this product and get back on the road and back to your daily routine in no time — with several hundred extra dollars in your pocket.

Review: I given three of this product to mechanics with details as how to use it. The product sealed the leak into the engines crank case. The only problem with it is that it is a long and time consuming treatment process (up to 24hrs.). But considering the money saving it is worth the trial. May I remind you that water in the crank case is a very corrosive substance and when you gets blown gasket, you should fix that right away.
Review: Not bad for price. The boyfriend swears buy this!!
