Best way to coat/insulate a header? Options

[KaptKaos]

Sort of a continuation from the previous thread about the eurorace header.

The header I have is used, but in decent shape. It needs a bead blasting and either a coating, or paint for sure.

I have read that people sometimes wrap their header to keep temps lower. IIRC, wrapping also traps moisture, which isn't good either.

I've seen some of those jet-hot coated headers and they look nice. I prefer flat grey, over the shiny finish, but I think they handle that.

Which option lowers heat more?

If I paint, what temp range paint do I need?

Where can I get the insulation wrap stuff?

Any other advice/experience is appreciated. Thanks!
