Hi All, I use 2x4s with the long up as roosts. I painted with an indoor/outdoor primer, then outdoor acrylic paint. When I took them out to clean with a hose, dish soap, and brush, the paint flaked off where the poop was thickest. Have any of you found a paint/primer that can stand up to this kind of stress, or is it impossible to keep paint bonded with this kind of abuse?
