Used it to thinly coat the mating surfaces of a used olive and nut which I had not replaced on a radiator valve, and the valve joint to the rad tail. Easy on, and no leaks.

Tasted awful on toast

Tasted so bad on my toast that I used it to seal an air leak - which it did well.

It didn't leak! So, if you think it might leak get some.

Good stuff.

Everyone says you don't need this but I prefer to use because it lubricates the threads and per joint it's very cheap. Bit difficult to get the smell off your hands though! Recommended by an amateur lol.

A good quality jointing compound. I use it on every screwed fitting including compression. Easy to apply, need less torque to tighten a fitting, makes dismantling easier years later.

Works well but I wouldn’t say it was ‘white’ it is more of a brown finish!

Bought this few years ago, kept well in the tin and only used it recently. It works well on olives in compression joints and on threaded joints.

Good product, works nicely on threaded joints and can be used on compression olives. Works well and no leaks.

Jointing paste works as good as expensive one.
