I was hoping to get one of those low cost, Arrow sheds from Lowes/HD to use as a coop for my chooks. My only issue is that all of my outbuildings (house, guinea coop, horse barn) are the same color and I would want this coop to match. I've read about how you have to use abrasives on galvanized metal to paint it and the same would be true with vinyl coated/enamel coated metal. Has anyone had any experience with this? Or painting one of the poly resin sheds seems to be the same process... I would love to hear any pointers or experiences with doing this sorta thing! Thank you!
