Every home mechanic should have some
Used this stuff for years, surprised it came unboxed and was not supplied with applicator nozzle, have contacted supplier who,s response was they were not aware it should

Packaging could be better
This stuff is the best you can get, Highly recommended by an ex royal royce mechanic and the only product he will use. My only critic was the packaging was just in a small jiffy bag which could have risked the product being damaged in transit, thankfully this was not the case for me.

Good enough for Rolls Royce so good enough for me
Using this for over 50 years, always a tube in my toolkit. It's always been the best gasket compound - it was good enough for Rolls Royce so good enough for me. Do not use though with a nitrile gasket as the solvent attacks nitrile. Apart from that why use anything else.
