I had a leak in the matrix of my oil fired boiler and it was getting worse, the garage floor was getting wetter by the day. I followed the instructions, which advise that I will notice the product working over the course of a week. The leak progressively subsided and stopped completely after 3 hours. I now have time to source a new boiler without panicking. Brilliant!

I was faced with minimum bill of £450 for a new heat exchanger in my gas boiler but for less than £10 your product did the trick. It has now been 3 months and no more problems. Thanks very much.
