    Horrible seller, I got sent the incorrect oil and incorrect filter, I contacted the seller multiple times and it took almost 4 days just to get one response back, I told the seller I ended up using the gasket and didn’t need the incorrect bottles of oil and filter he sent me anymore and to give me a partial refund. He sent me the refund label and once the item was received he then contacts eBay and says that I opened the bottles and spilled the oil and kept the gasket even tho I told him.

    Permanent repair, working so far.

    Worked as advertised on my heater core leak, I have never believed in products like this before but had nothing to lose in this case, I am pleased to say it worked for me.

    This saved a recent install of mine! I had replaced a Toyota water pump, and no matter the torque spec, it had a two drop leak each time the engine shut off. This sealed the small " seepage leaks" and is still holding strong! I'm going to start using this, instead of silicone on coolant gaskets. A million thanks for the good price, and prompt delivery!

    It works!

    My Rover 3500 Aluminum V8 was using a bit of water. I suspected a crack in the block or a slipped liner, which is common with these engines. I don't normally have much faith in such products, but was impressed with the positive reviews on K-Seal. As a "hail mary" I tried it. It works. The motor stopped going through water within ten minutes of driving and has not used a drop since. It has been 500 miles and I would normally have gone through a pint. Great product!
