No Nonsense External Leak Sealer 50g
Save your Money, Doesn't Work
I bought this for a tiny leak on a radiator valve. The product looks and smells exactly like ordinary clear silicone sealant. The leak was from the 12mm micro-bore joint into the valve. I tried several attempts but it just kept leaking, only a tiny drop every five minutes but the sealant couldn't stop it. Looks like a full drain down and new valve/pipe is the only solution. Don't waste your money!

I use this instead of/as well as PTFE tape and it does the job well. It is 60% of the price of the brand name product, but 100% the same.

No Good Leak sealant
No Nonsense External Leak Sealer did not seal the leak from the radiator valve connection. It did not adhere to a wet surface as claimed and was no better than ordinary silicone sealant, a large tube of which is much cheaper.
Managed to seal leak using self amalgamating tape.
