I painted my Orion silver to break up the expanse of black, but that is more noticeable. I think on a darker colour doesn't seem to make much difference, unless you silver the borders of the left right grilles.
I also painted my mesh grilles gloss black, they stay cleaner longer and show better contrast.
Nothing on the lights. It's the dividing piece between the lower left grill and the lower centre grill. Only did it on the left side. I've got a space grey aerosol to paint my new door mirror cover when it arrives so thought I might try painting these at the same time.
How ironic, this is exactly what I started today. So far I've removed the lower grill surrounds and the dividing trim between the centre & outer grills. Haven't got the paint yet so prepping for its arrival. Looks way better in my opinion.
