That DIY is not a good one if you have angel eyes which I assume you do. He demonstrates how to open halogen, non-xenon lights in that DIY and if you follow it to open xenon lights, you'll break the angel eyes. I know because that's how I broke mine. I posted an in depth DIY of opening xenons, how NOT to break the angels, and how to install LED angel eye rings awhile back but if you don't want to hassle with that, I'd recommend sending your headlights to Marc - user MDS82. I bought my silver carbon fiber covers from him to do the work myself, but he can also do the install. It'll cost a couple hundred more than painted overlays, but will be well worth it. Overlays look tacked on, his CF covers inside the headlight look OEM. Here's a couple of pics of mine in silver (also available in gray).
