Nothing more than silicone The product is simply a small tube of silicone sealant and should be advertised as such, no better no worse but don't expect much from it 23 Jul 2015
No Nonsense External Leak Seal Great buy, almost half the price of other branded products. It worked really well when dealing with a radiator header tank. It was no where near as smelly as other brands and when working in a closed in roof space with no ventilation this proved a real bonus. It was also easier to apply and tool than other products. Will definitely buy and use again. Have give 3 start for reliability as I have only just put it on, otherwise a 5 star product. 2 Mar 2015
THIS IS A JOINT SEALER 'External leak sealer' is misleading. This is a joint sealer, for compression or threaded fittings. I can see I would use this if I had a compression fitting which was weeping and I couldn't get it any tighter. In fact, the best name for this would be 'Small Tube of Clear Silicone Sealant' which is basically what it is. I bought this for a temporary fix on a pin-hole radiator leak which it was totally unsuitable for. Isn't that an 'external leak'? I actually needed some Araldite. 24 Jan 2015
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! 19 Jan 2015
