    Rated 5 out of 5 by Perfect Garage wanted to fit a new radiator.(£100's) Radweld did the trick in 5 minutes for less than a fiver!!!! 22 October 2016
    Rated 4 out of 5 by Great product I used it to stop the Ford Fiesta 2006 radiator leakage which was quite intense. It did stop it as expected although the instructions were not quite clear so I just poured it into the overflow container and kept the engine running for a while. The next day the leakage was gone. Great price/value !!! 14 June 2016
    Rated 5 out of 5 by Works well I have a cracked head gasket so it'll help my car go a bit longer 20 May 2016
    Rated 5 out of 5 by Very easy to use This product was really easy to use - a 15 minute job. It seems to have done the trick! 02 May 2016
    Rated 5 out of 5 by This stuff works! Had a fairly slow coolant leak on my Clio resulting in the coolant level going from max to min after about a week. Put a quarter of the bottle of this stuff into the coolant reservoir (as the car has a small engine, it didn't need a full bottle) - ran the engine on idle for 30 mins. Done a lot of long drives since I've done this treatment and my coolant level hasn't budged once! Really happy with the result 01 May 2016
    Rated 4 out of 5 by Used to stop gasket leak over belt which was squeaking Not a bad product considering. however I did have to buy three of them until it stopped the leak and almost took three weeks to work..still cheaper than the massive repair 07 March 2016
    Rated 1 out of 5 by Does not work Bought this as a temporary repair for a pin hole in a water pipe until i could get a replacement hose. Followed instructions and it did nothing other than stop my heaters from working! Now need to have system flushed and a new heater matrix. Avoid at all costs, expecting a hefty bill from my mechanic now. 19 December 2015
    Rated 5 out of 5 by Should be kept in every cars boot Very impressive performance on sealing head gasket leak on my old Ford Sierra, which was pressurising the cooling system No nasty side effects either. Always keep some in my boot now , just in case 28 November 2015
