Brand new beek here. I am studing, reading and starting to buy equipment for the 2015 season. I love the warm natural look of stained wood so I want to stain and seal the outside of my hives. I was watching a video on utube about sealing stained hives with fiberglass resin but he didn't elaberate. What, in your opinion is the best substance to seal and protect the wood of our hives?
