Looking for a Super Steel Sealant 2!

| | | | | | | | | | | | |

I don't know if my previous question went through. I MIG and TIG steel sculptures. I am looking for advice on cleaners and sealers for ferrous metals. I have used cold patinas (I am unable to use a torch right now -- this may change), and Permalac with a wax coating. The result indoors and out has been rust. I can accept a certain amount of rust, but I would rather not.
