We have used the sides of an old discarded stove to make bumper plates on the inside of our shed doors to protect the doors from hits from our tractor or other object as we back out. Those panels can take a beating!
The bonus of this is as we collect more discard appliances line the bottom part of the inside of the shed we’re getting all sort of useful storage space between beams for storing tools, poles, and whatever other thing we can slide in there.
