I have a few metallic paints in Vallejo, humbrol, tamiya and alclad. The humbrol and tamiya work well, but I find them to be too shiny for small details
Most of those buttons and switches are gray not metallic. I used a light gray on my recent Hornet build, possibly Light Ghost Gray or Neutral Gray, I don’t recall which. But for smaller metallic stuff, Humbrol 56 works great. It’s a bit darker and grayer.
