What is an appropriate semi-permanent surface to use over an open fire barbecue? I am planning on making a grill rack for my fire pit. My intention is have this surface remain outdoors within the pit. I'm looking for something that wont corrode and that is food safe and something that can handle the high heat of a fire pit.
I have seen sprays that can be applied. Some are high heat sprays made for grills (exteriors). I'm not sure if these are food safe. Has anyone had experience?
I have also seen food safe anti-corrosive metal sprays, but I cant find information about their heat tolerance.
Thank You for any help.
