I opened it around 5 months ago and I did put the top on tight, I would like to use it for the clutch master, but if it's no good I won't. Thanks!

Is there a shelf life on this stuff? I don't know.

You'll be fine using it after it's been open for awhile, just make sure nothing gets in it.

I was always told that it would go bad .But I did save it & reused it on my 56 when & if need it .....................:patriot:

I think that you'd be OK for months, as long as it's closed tightly. Left open, it's probably shot w/in a few hours.
