Thanks Mando Assasin!
I can see Fix It online and could buy it from EBay or Amazon, but the airmail postage makes the price at least double which is the UK's problem!
Hence why I wanted to see if there was a UK version, this works exactly the same way, but comes in smaller amounts, I bought 113.4g for £3.99 with 99p for P&P on EBay.
It goes a long way as you only need very little of it, but it has all the same properties as Fix It and comes in various colours.
