Nonsense. Paint isn't a perfect covering and unprotected PT is a
disaster waiting to happen. Have you ever seen painted wood in
contact with the ground? Does paint stop a carpenter ant or termite?
How about uncoated PT left out in the weather? Again, nonsense!

I've seen lots of painted and unpainted wood in contact with the ground.

So have I; all rotting.

Termites don't eat paint, and all of the many carpenter ant problems I
have seen were in dead or rotted wood.

Nonsense. Why do you think treated wood is used?

PT only delays the inevitable....eventually, in or on the ground,
termites will probably invade without any other barrier. Carpenter
ants, at least around here, do no infest sound wood.

Delays for *years*. Ants, termites, and other critters really don't
like the taste of copper and arsenic.

The OP asked about siding, which
I would not put in contact with the ground. Don't know how cedar
compares, price-wise, with any other siding, or whether other woods are
available for the same style of siding. My question remains...why
choose cedar if you are going to paint it? If you are going to paint
it, you seal it up tight and keep it that way.

You use cedar because it naturally resists pests (PT does the same
"unnaturally"). It doesn't resist sun or water, so must be
protected. Paint works.

Precisely. Now, back to the point I have been trying to make.
Weathered cedar is pretty, long-lasting. But, if you cover it with
paint to protect it from sun and weather, why not use less expensive
wood if you intend to keep the paint in good shape?

Because cedar is *NOT* naturally weather resistant. If left
unprotected the sun and water will get at the lignin and it'll come
apart. You really do need to put something on it to protect it.
Paint is one of the options. Even if both are
painted/stained/whatever, cedar will outlast pine or such.

PT doesn't last forever, and, for sure, should be the choice to put in
the ground. I'd dip the bottom in tar first because bugs will get into
it eventally. Could probably do as well with non-PT? Takes about 2
years here for termites to get into PT.

Nonsense.
Nonsense, nonsense, nonsense. Let's talk about something you know
about, not something you think you know about.

You are obviously ignorant of the entire subject if you think
termites will eat two-year old PT. There really isn't much hope for
you.
