Used half Halh
Used twice and it worked (1 week gap). (Or try using 1 bottle half half). I also replaced my cap on my coolant reservoir. Its over a month and all is good so far, as previously i had to topup coolant every week from Minimum to Maximum level on the coolant reservoir. I used it first on a slightly warm engine, for example, leave the engine on from cold start for 5 min (be VERY careful when opening the coolant reservoir cap). On my second attempt, i poured it straight to a fully cold engine. For both occasions, after pouring, i let the engine run for 15 mins with all heaters at high heat, slightly revving the engine every 2/3mins. EDIT: 2 months in, it slowly leaking again (but lot less than before). Appears to be temporary solution.

Actually worked
I changed my car 4 months ago to a 10 year old Ford B-Max. After driving it for around 3 weeks I figured I'd better check/top up screenwash. That's when I noticed the coolant level had dropped from max to below minimum. I topped up with coolant and checked again a week later, comparing photos I could see a definite drop in coolant so I topped up again. This car was supposed the help me save for a mortgage deposit so the last thing I needed was extra bills. I tried this Holts Radweld and have to say after initially dropping its holding steady. Including two 390 mile round trips so engine was well worked. I topped up coolant with Radweld (managed to get full bottle in) and drove for about 25 minutes. Only afterwards I read that heater should be left on full for about that time so that could be the reason for dropping slightly. So happy it's saved me a trip to a garage.

Easy to use
Performance wise, it seems to have cured the leak on the first try, although the car hasn't been for a run yet. Good value and quality, easy to use.
