Anyone wonder why it isn't hard to get the lid off of a Loctite bottle.

Do those old bottles still work for you? I have always thought Loctite had a pretty short shelf life.

I've used them and never noticed a problem. Some do seem thicker & hi-temp ones definately are discolored.
Guess I should do some tests. I'll put a nut on a bolt & see how they seem. It'll be a while, as I'm in the middle of moving & they're buried/lost right now.
Most of them are from the Speedway, earliest are '87 IIRC. They'd give you a kit in a metal box with a Loctite sticker on it. This was before Permatex bought them out.
Even the unopened older bottles start to get sticky & ink smears, so air in bottle seems to make no difference, but might.
