Cedar he supplied. To be finished with clear poly. Anything special
I need to do to cedar before applying the poly?


Testing on scrap is always good advice. If there appears to be a problem
with the oil in the cedar letting the finish cure, try a coat of ultra
blond shellac as a sealer on the cedar. It will darken the cedar a bit and
add just a hint of yellow, but nothing you could not live with. Since
shellac is the universal bonding agent, the poly will have no problems
going on over the shellac.
