I built a custom stainless header and wanted to give it some extra protection, so I gave this high heat rustolium a try. I read the directions and applied over the sanded cleaned stainless steel. Let it dry for almost a week and installed it, and noticed it was chipping off very easily and I was able to scrape it off with my thumbnail very easily. I would not recommend this product for clean stainless steel. Maybe it’s better for old rusty metals I don’t know.
