This may seem a little unusual, but I converted my unit into a humidity controlled spray booth for finishing guitars with waterborne lacquer. My finish requires 45% to 60% relative humidity for application, and typically here in New Mexico, I see less than 30% RH. I put a humidifier in the shed, and cut a hole for an exhaust fan. Sure, it voids my warranty, but worth it ! This shed/booth sits in my garage, is well built and sturdy, and I would not hesitate to use as a storage unit outside, even with the high winds we get here. The anchors are solid.
