4 years ago I put my 65 fastback and 57 chevy belair in storage and moved overseas. I bought a shipping container put it on my uncle's farm. I am moving back to the US this summer and I am having mixed feelings about opening up the container. My uncle prepped them for storage, so I am sure the engines will be fine. What I am really worried about is rust. The container is supposed to be watertight, but the air in Georgia is always humid. Should I be worried?
