I also bought some high temp ceramic coating spray paint in attempt to do something about my completely rusted out headers. I attempted to sand them out but got frustrated and conceded to acknowledge that I will just need to buy new ones. I had already bought the paint and thought, what the hell and see how they would turn out. I was pleasantly surprised at what they turned out to look like with one coat. Not sure how long if at all coating will last but damn sure happy with results.
