Touch-up "paint" for Pardini SP finish?

[Questor]

The top of the barrel shroud on my SP has some of the finish missing between the grooves that make the top of the shroud less reflective. It's minor, but I'd like to touch up the finish if possible. Is there such a thing? I believe the finish is parkerized, but I'm not sure.

I was wondering about this, too, but in a different area. What is the material covering the frame of a SP and can it be touched up?

I touch mine up frequently so it stays in pristine condition.
What works best is Birchwood Casey G96 Gun Blue and Aluminium Black. Follow up with Tetra Gun Grease...
