I recently bought this grill to replace my existing broken grill. It's all black shiny plastic.

I want to paint it to match the dark blue frame & gray grill. I can get color matching spray cans easily. Do I need to do anything to get the finish coats to adhere properly? Some sort of primer? Sanding the egg crate portion would be quite a task. Thanks for any thoughts or experience.
