We have used Regalrez 1126 in some situations on wooden objects,
usually as a barrier coat or as a saturating varnish.  The
properties of Regalrez meet all of your criteria.  But Regalrez is
so soluble in aliphatic hydrocarbons that it can quickly and easily
be removed mistakenly; such as if a paste wax were to be applied
over the coating.  I would also point out that Regalrez saturates
very well and could change the appearance of your panels.  Testing
is advised.  I would also strongly recommend using 10% Kraton G as
an elastomer in the Regalrez solution because Regalrez is very
brittle and scratches very easily.  A good article explaining the
properties of Regalrez is "Regalrez in Furniture Conservation," by
Hans Piena in the Journal of the American Institute for
Conservation, Spring 2001, Vol. 40, No. 1.
