iv got mine painted white, just use a small flat head screw driver, and just go along and pop it out from your front grill, just dont scratch the black or use so much force that u snap the red stripe :) it is easy realy :)
clean it with hot soapy water then also get some very fine sand paper rub it down, prime it, then sand again, then paint then laquer it :) i just drove round for 2 days without it whilst i painted it :)
then just clip it back on and your done :)
