Default 5 year-old latex paint.

Funny you asked this today, I had just been thinking how silly I was to
use some old paint I had left over.

I had some SW latex trim and shutter paint that was at least that old.
It was really good outdoor paint that I'd had great success with. I
used it on outside windows two years ago and it was fine. Last year I
used it on an outside door, and it worked just fine, until summer came.
Now although it FEELS dry to the touch, the damned door sticks as if
the paint was still tacky.

I think the paint would be fine if I was painting siding or trim, just
not on moving parts. The thing is, painting is such a chore, and gets
really ugly if something goes wrong and you have to remove or sand the
stuff and redo it, it seems not worth taking the chance. My problem is
I have a hard time wasting anything, and more than once I've been penny
wise and pound foolish, something my mother had warned me about many
times in the distant past:-) I don't think I can change though, so my
recommendation is give it a shot, see what happens:-)

Not directly related to woodworking, but I am hoping to paint some
stuff on the outside of the house with a couple of gallon of Benjamin
Moore Exterior Latex of a particular colour which I have in inventory.
However, those two gallons were mixed 5 years ago, but upon opening
the cans, all seemed well, just a tad of separation on top, no lumps,
smelled okay, tasted fine.
My regular paint guru is on vacation, and I know there's well-honed
knowledge base in this group.
It will be going on treated wood and steel, the same I did 5 years ago
(The building of a deck interrupted the painting ofd the back of the
house.... and then I got busy with other stuff.)
What I painted 5 years ago, still looks spiffy, even after a few
powerwashes at 3000PSIG.

So, what do you figure, gentleman, ladies, should that paint be okay?
Or do I shed that genetic Dutch Fault and throw it all out and drop a
hundred bucks and buy new?

all thoughts appreciated, and shall Google some more...
