Just run straight through and failed to seal tried second bottle and did the same .

Simply did not work. A expensive failure.

Bought this product from e bay but having difficulty leaving a review on that site so posting here.I bought a 2001 Mercedes C180 Estate as a 'Trade Sale' car from a local garage. It had been well looked after by its first owner (the bodywork is still in great shape) but as was disclosed to me by the vendor rather neglected by the second owner. Got it home to discover inter alia the water pump had failed . Replaced the water pump and thermostat and discovered the head gasket had gone by using the excellent diagnostic kit supplied by the vendor. I was advised to scrap or sell on but decided to see if I could make something out of what everyone thought was a nail. Gave the cooling system a thorough flush and then 'double dosed' (probably unnecessary) with this product. Lost probably half a liter or less of coolant over the first 100 miles but since then I (deliberately) haven't topped up to test the durability of the repair. I have covered 5000 plus miles since the repair during this past long hot summer and just returned from a 1500 round trip to the continent driving. The trip 'out' was not without incident (the air con pump failed) but I drove back continuously averaging 70 MPH. I have checked temperature pretty regularly over the last six months and its been constant indicating everything is now in order. I can't warrant the product coz I am no expert but it has worked exceedingly well for me ....A permanent repair ?? I would answer yes in my case in that I reckon the car will give up before the repair
