Not surprising. This site has the worst "search" function I ever tried to use. I can't even find my own posts.

If you can find the colors you want in NHT paints, clean the parts in Dawn Power Desolver & let them soak overnight in vineger to etch the surface.

Apply VHT paint, let it dry, then bake it in the oven @ 300°F for a few hours.

I have used Rustolem flat aluminum BBQ paint W/good results on the case. It has stood up well to 30% nitro fuel.

Unfortunately it only comes in (flat) black aluminum & dark green.
