It seems like every company under the sun claims to sell the whitest, brightest, most reliable, cheapest, easiest to fit, error free replacement bulbs however having tried 3 different ones now, they either don't fit, mess up the electrics or aren't xenon-like! Can someone please advise me on the best/cheapest solution? Thanks in advance... :)

Is it that easy? What type of paint should I use to ensure that it doesn't peel or crack etc? Is there no-one out there that sell black replacement ones!?

What is the easiest way to de-chrome the exterior trim around the windows on an E92? I'm going for the black stealth look! Any ideas?
