I installing some Red Cedar closet boards in a motorhome as panaling,
because it looks
nice and will kill the motorhome musty smell. I need to finish the cedar
with something,
but I'm sure polyurithan looks nice, but will kill the fresh smell.

Currently I'm thinking of cutting panals of the 1/4" cedar chip board and
glueing the
cedar boards to that and leave a 1/4" air space in back so I can use the
polyurithane on
the front side and still let the back side breath.

Does anybody have a better idea?

The poly would undoubtedly surprise you as the oily, resin-soaked cedar
discarded it. Leave it bare both sides, the stuff burnishes pretty nicely
with no finish.

Never finish only one side of anything - recipe for disaster.
