Need some tips for my custom!

[DemonicGods]

Hello! I need some help with painting. I need to know which paint I should use for my figure. I am customizing a 6 inch Clone Commander Cody figure. I am planning to make a custom Commander Thorn figure. I have already spray painted the visor gray and used a dremel to remove the extra bits on the helmet. I'm going to swap the head and use the plain clone trooper's body. I think I am ready to paint the helmet, but I need a paint that is durable and easy to work with. I am not quite accurate on painting, so can anyone provide me with tips on how I should paint the wings on the helmet? Thank you for reading!
This is the basic design for Commander Thorn.
