I have been painting with oils for 5-6 years. I have also used acrylics.
Long ago many oil paintings were done on wood. These paintings still exist
because a thick base was placed on the wood first. This gesso base used to
be organic (horse glue etc.) and is now acrylic. It is OK to put oils over
acrylics. The thicker the gesso the better. You may still experience
problems if your wood base is not completely seasoned (dried out).
Alkyds are compatible with oils. I now use alkyd white with my other oil
colors. A complete switch to alkyds is not that practical because they are
more expensive than oils. Depends on how much you want to spend.
Don't forget to use gesso even on canvas. It is theorized that oil will
eventually deteriorate canvas. Give the painting 6 - 12 months to dry. You
are obliged to sell only quality products if you are an ethical artist.
The surface remains soft for a long time.

Having considerable experience as a dealer/curator with oil paintings
of varying age, I strongly suggest applying a ground (or 'gesso') to
*both* sides of the canvas. Paintings which survive without a flaw are
often those that have *another* painting on the verso (canvas is
expensive). You want to preserve the canvas' and oil paints'
elasticity while preventing oxygen from access to the top *or* bottom
layer of paint.
An interesting discussion dervied from this would be, 'why not paint
finished pictures on *both* sides of the canvas?'

I believe the manufacturers of Alkyds make the claim that these paints dry
to form a more resilient and flexible surface than oils, and should
therefore be more durable. They are also said to be okay for a wider
range of supports than oils (correct me if I'm wrong).
I have used Alkyds to do monochrome underpaintings as well as sketches.
There are sketches I produced some time ago on very cheap cardboard
supports that have been treated roughly, yet seem to look as good as
new---better than I would have expected oils to look. I would bet that
Alkyd paintings could withstand cleaning better than oils too.

Hmm. But there is a difference between quality and everlasting. If your
paintings are capable of lasting a couple of decades, your customers
should have got their money's worth out of it by then (unless you are
priced in six figures or more, in which case the cost of restoring the
work will probably be lower than that of insuring it).

Wouldn't there be a marketing problem with this, perhaps? I mean, it
seems unlikely that you would be able to charge double the price for
double the painting, and of course it might be harder to find buyers who
like the pictures on both sides.
On the other hand, amusing (perhaps rather gimmicky) creative
possibilities suggest themselves, whereby the painting on one side is
somehow related thematically to the painting on the other (they could be
variations on a theme, or one could ask a question that the other answers,
etc.).
