Not sure why but I haven't had success with ceramic coating staying on my headers. Not sure if it's something in the air in NYC
, or the gravel & pothole strewn roads I ride, but the coating doesn't last more than 6-9 months for me. Don't go by my experience, I seem to be the exception.... don't know why.
I'm currently on a second coating which has worn off, so this winter I'm wrapping my headers instead.
this is what my header looked like this past April, about a year after these headers were coated...
