I hear paint has a _shelf life_, where it is no longer "good". Have a
5 gallon unopened bucket 9 years old and I'd hate to throw it out for
the time being. It must be good for something.

I've used some oil-based exterior paint that had to have been 40 year
old that Dad bought closeout stock from local farmers' Co-op when they
closed the retail store. It was, as far as I can tell, as good as new,
both in application and in holding power (it's been almost 10 year now
since first that used and I can't tell it from the other that was new at
the time).

I've also quite a stock of going-on-10 yr-old latex from the barn refurb
that got sidetracked, also that seems no worse for wear; no reason to
think as long as it stays sealed any different.

Thanks. Comforting to know. Tried to sell the sealed plastic bucket
of latex at a yard sale. I'll keep it, mix it well and strain it
when I do open it. (latex elstomeric stucco paint)
