So far, so good!! I'm very happy with it. I do think I'll do another coat this summer and go a little higher up on the walls. With the original application I didn't go up onto the bottom 2x4, so I think I'll do that and go up about a foot.
We are finishing our coop this weekend and I'm now desperately trying to find Black Jack #57 near me. I saw someone said they got theirs from Ace, but I don't see it online. I'm going to the store tomorrow and hope to find it then! Other than that, I can try Walmart or Aubuchon. Surely...
