yeah it needs painting alex

Colour code it, otherwise it will look like one of those cars you see driving around where they have bought a different colour door (or boot, or bonnet) from a scrappy and can't be arsed to paint it.

Or like an old mate of mine who drove around with an unpainted cheapo bodykit on his Escort for the entire time he owned it

Definitely paint it
