Hi all, I'll preface this with... I'm a new beekeeper. :) The outer cover on both of my new hives is very hard to take off and one of them won't go back on all the way. I was lucky that I had the cover on the upper deep with no frames as I'm feeding new packages now. I painted the inside of the inner cover, but maybe I should not have done this. I followed the painting instructions in the 'Beekeeping for Dummies' book. In any case, what can I do now to fix them? Do I have to sand them? How should I fix this?
