I bought the pair on my car over 20 years ago and I swear that at that time they came with a "lifetime warranty". I find that Sanderson has now reduced that to only five years. It doesn't matter - I lost the original receipt years ago, anyway.

The reason this matters to me now is that they started rusting through the ceramic coating in small spots about ten years ago. I had stopped using the car and just let it go, but now I'm getting the car back on the road and would like to refurbish the headers. I don't think the condition has worsened in storage, but it didn't heal, either.

Before I contact Sanderson about re-coating these, is there anything I can do, or any product I can use to restore them to the unattractive dull shine they originally came with? Yes, that's a bad attitude, but even the dull shine is an improvement to the rusting I now have.

I've tried various "chrome polishes", metal polishes, and rust removers, including EvapoRust, to no avail.

These headers have been fine otherwise, even if I was disappointed with the original finish (my fault, not theirs). They fit tight and even, don't leak, and solved some clearance and overheating problems I had, so I'd like to keep them.
