Some clown is going to polish it up to within an inch of its life. Powder coat the frame. Then will come the 6 coats of two pack paint, just like it was when it came out of the factory. Not. Everything nickel plated will wind up chromium plated. All brass will shine and gleam. In short, it's going to get ruined.
I agree with gerhed, it's fine just as it is. Put it on a stand and leave it at the side of the shed just to look at.
