I have a 12 yr old platnium, looks like a performer, and the two legs under the grill bowl are wheels but the legs under the table are 3/4 or 1 inch metal tubes. The tubes have become very rusty where they sit on the ground and up about 2-3 inches, leaving rust stains on my deck. Plus, in another yr or two, the legs will crumble. Has anyone else dealt with this or have suggestions on a relatively simple fix?
