Hey all, I'm new here. My son was moving my 22" Kettle and accidently dropped the top in the driveway. It has a pretty nasty scratch on it. I don't mind the scratch but I don't want it to rust so I'm here for ideas on how I can protect it. Paint, Polish, Protectant... Oil? I figured you all would know what to do. I also noticed that the vent on top doesn't have a date code or serial number... so I wanted some thoughts on that as well. I'll include some images of the kettle.
