Yup that works!
I cut the sides off of old fridges,washers and dryers and use the metal for many types of repairs.Its completely rust free,has a very tough finish (probably baked) and is about as thick as a traffic sign.And you dont have to wait for it to fall on the ground,lol! How many folks have these old appliances kicking around?
The thing I really like is you can get very large sections from fridge sides.
Any appliance will work really.
