Hopefully someone can give me some advice to remedy this situation. Regardless of what I've done thus far, my headpipe continues to rust. It's not a deep, penetrating rust, but more of a surface rust. I've tried the old scotch-brite/wd-40 trick with no success. It looks good until I start it, but after a minute it's back. It's not a performance issue, but it looks bad, and I somewhat worry about the longterm effect of corrosion. At this point I'm considering some sort of a rust inhibitor, or hight temp paint. I'd welcome any advice. Thanks in advance.
