I replaced a chunk of siding on my house and now I need to prime and paint
it

Question in my mind is, should I go with a latex or oil primer? I only ask
because while I KNOW the paint on my house now is latex, when I get the
siding painted again I'm not sure if at that point I should go with an oil
or latex paint.

I have heard that oil paints are increasingly not used anymore. So I'm
wondering if I go with latex now, am I stuck using latex in the future or if
I go with an oil now, will I have to reprime with latex later.

I'm just wondering what would be the best route to go given that 1) the
current paint job is bad quality 2) I will repaint the house in the future.

Also, when painting cedar trim INSIDE the house (window trim and the like)
and you want to keep the natural cedar color - would a normal polyeurethane
coat do the job or is there something specific to cedar?

Oil paint is getting more difficult to find because of government
restrictions for air quality. Some regions are not allowed to sell oil
based paint because of hte VOC content. You may as well get used to using
latex now.

ABSOLUTELY!! We should all do our part and stop using oil paint.
That way, we'll be able to have more cars :)

We should also stop putting in lawns...watering them reduces the
number of golf courses (or is it vice versa, I forget). We could also
flush just once a day.

Any way we can pass a law against congress?

Latex dominates the marketplace and is fine for most siturations
including yours. Oils can still be found at a real paint store and
are still good for problem surfaces or surfaces that are expected to
get wet like bathrooms.

You say that you are replacing the siding. This suggest a problem
with water damage? This would be the type of situation where an oil
might be used. Ultimately it's your call. I rountinely use an oil
primer on a surface that is expected to get wet.

No, you will not be stuck. It is good practice and quite common to
put latex over an oil primer. It is considered not so good to do the
reverse. Before anyone disagrees, of course it can be done just not
recommended.

It is unusual to use cedar inside the house but Poly is OK. There is
no finish specific to cedar. A penetrating stain is often used on
cedar in an outdoor situation but I haven't seen it used indoors.

The questions I have about oil primer covered by latex:

1. Different expansion rates. Won't they eventually separate?
2. Oil primer will prevent house vapor from leaving walls.
