I am a newbie and in my over zealous approach to hive maintenance, I stained and put 5 coats of Minwax® Helmsman® Spar Urethane (A protective clear finish topcoat that offers long-lasting protection for interior or exterior wood that is exposed to sunlight, water and temperature changes) on all the wood parts of the hive (inside and out) 4 weeks ago and plan to install a package of bees on Monday 4-21-08. I have since learned I am not supposed to paint the inside. What will happen if I install the bees in my stained and Urethaned hive?? I even sanded between coats which I read makes it too slippery for the bees. Should I sand all the finish off the inside?
