I painted the grill with so called satin black (I don't know White Knights idea of satin paint, but much nearer to gloss doesn't qualify to me). I would recommend going matt or don't paint it at all.
Just as well it will get dusty soon enough. I prefer how it was. Live and learn.

While we're on yellow as a theme, I thought I'd include a pic of a hubbo on my car's wheel. I filmed it with an action camera. Fun times.
