I finished mine a few months ago, split the headlights painted surrounds and resealed. Fairly simple stuff, the mistake I made - and it was a huge mistake - was to try and clear coat the lights for more protection/shine. I'd watched some youtube videos of people clear coating with great success, apparently they wern't using acrylic. When I sprayed the lights they looked good for a few minits then they literaly melted! The fist milimeter or two of the light surface crazed like a turtle shell. I ended up sanding from 300 up to 2000 to get a clear lense again - literaly days of sanding and polishing.
Anyway, the process is all over the net, take out the screws (about 3 or 4 from memory), bang em in the oven and pry them appart (google the temps). The lights are made up of lots of pieces, so painting them is easy. If you want to get rid of the orange indicator you need to cut it out, I just wanted my lights back together at this stage. A full weekend is just enough time to do it right. I used auto paint for the satin black - no clear coat. I wouldn't try and polish the inside, it has some tight corners that would be virtualy impossible to do right.
