I have that M3 lip on mine and it seems to be holding up fine. I didnt actually instal it but Im sure it was easy to paint since my car is flat black... I dont know wat color your car is Pete, but if it's a common color, it shouldnt be too hard to paint.

 

I got it off of ebay from trimking... it will come painted already. I will let you know of the quality once I get it.
