Ordered the Charcoal Lamin-x for my heads, fogs, and tails last week. I will post pics when I get it installed.
As far as fitment on 3rd gens, they say its quite flexible when heated and recommend using a blow dryer or heat gun to warm it up, especially for lights with lots of nooks and crannies like the 3rd gens.

I've seen this stuff on a few trucks and it looks very nice. I can't speak for the ebay stuff, but the lamin-x is high quality material.
