CTEC Miracle Seal - Sealer for Minor Leaks in Heating Systems, Hose Pipes & Water Pumps - Suitable for Metals - 250ml

Didn’t work I can only give it one star which is the minimum rating. Ideal it would be no stars.Don’t waste your time. I got a man with a thermal imaging camera to come over and find the location of the leak and sorted it. Wasn’t even a large leak and the advertising for this stuff shows a much bigger leak being sorted. False marketing I’d say.

All it had to do was a pin hole in copper pipe ,same as most 'in a can' useless should have known better can reads like a miracle cure

Saved a lot effort and time--worked almost in an instant--------recommended.
