I reckon they must only sell it when a tin gets squashed or left open and the blue dries out.I've had my tin of micrometer blue since I was 18 (72 now). It wasn't new then, I inherited in the contents of an uncle's tool cabinet. He was a toolmaker by trade and had made good use of it.

That’s the only reason I got a new tin to replace my 50odd year old tin. My 1/2pint tin of valve grinding paste that I acquired used around 1970 will see me outI reckon they must only sell it when a tin gets squashed or left open and the blue dries out.![]()
Add a few drops of thin oil to the hardened cake and put the lid back on ?I reckon they must only sell it when a tin gets squashed or left open and the blue dries out.![]()

I also had to put my hand in my pocket for a valve grinding tool this time (old school stick with rubber suckers..)I bought a tin of copaslip when I first had my workshop in 1985. I remember wondering how long it would last me.I've managed to acquire at least 3 tins over the years, same with Copaslip.
I got a tin of AluSlip Ages ago, now that's a multi-generational purchase.I've managed to acquire at least 3 tins over the years, same with Copaslip.

..same here. I learned today whilst buying disks and pads for the car that it's no longer supposed to be used on brakes - so I have even LESS to use it on now...My tin of Copaslip must be hetting on for 45 years old. Still three quarters full.







I had a tin of Never-Seez, blagged from work in the early 80s. Only finished it a couple of years ago and bought its replacement at some knockdown stock clearance price. The full price nearly made me blanch, and had put me off buying it for ages.My tin of Copaslip must be hetting on for 45 years old. Still three quarters full.
how strange my tin showed up a few days ago that i got given 55 years ago forgot i had .it was in the back of the cupboard used it when i was rebuilding motorbike and ford engines many moons agoHas anyone ever in the history of engineering used a full tin of Blue? Stuff lasts longer than valve grinding paste.
