Heres two links to doing the mod. Link 1 Link 2
I'm actually in the middle of doing this mod. I put mine in the oven at 250 for 20min and it came right apart. I followed the first link cloest. I used steel wool to scuff up the chrome part I painted and it worked great.
Just don't put the head light directly onto the metal grids. I first put down a pizza pan then put down tin foil on top the two pieces of 2 by 4's and layed the light on top of that.
I've only got one done right now cause I havn't had time to do the other one, but it looks great.
What I recommend doing, which is what I did, is buy a seperate set of headlights and doing the mod on them and then putting them on your car. It's best to do it that way incase you end up not liking them you can just swap them back out and sell the modded ones. That way theirs also no down time on your car while the headlights are off and getting painted. I got my extra set for $40 and they were in great shape, theres a set in the FS area right now.
