Spar Urethane

I'm installing two more hives tomorrow-- that'll be another post. For these hives, instead of paint, I coated them with spar urethane, meant for coating outdoors wood. It's resistant to sun Specifically, I used Minwax's satin spray spar urethane.

I don't know whether or not this will have a negative effect on the bees. We'll see. But the spar urethane (especially the spray) seems a lot simpler than painting. Plus, I like the natural look of the wood supers.
