This product really works so simple to use. My heater core had a leak and kept putting steam on the windshield after following the instructions, added to the truck water system, the problem has been resolved for now, and I know this is just a temporary fix, but still really helps, and saves money in the winter, cause I need heat. If I need to redo the process again I will, but its been 1 month and holding. The cost for heater core replacement $3200, this product $45, if I need it again, still worth it, it would take 75 times using this to equal the replacement cost, so, each and every other month, I will reapply the product, and roll with it. Great product for my vehicle.

Blue Devil Head Gasket repair is the real deal! Super easy to use, worked instantly! seems expensive at the $ 30.00 I paid for the small bottle I bought but compared to the $2,000.00-$3,000.00 to have it fixed in the garage not to mention the wait time of 2-3 weeks before they could even get to it, I was able to drive my car no more than 30 minutes after applying Blue Devil!
