have you done anything like on any other car previous to this mod?hmmm..it really isn't that bad. just takes lots of patience. bake in the oven at 220 for 10 mins, take out with oven mitts and gently pry apart. putting them back together is just as easy. bake in oven at 220 for 10 mins again, press back together making sure you get all the clips in place. once it's cooled and back together place in oven again for another 10 mins, take out and do one final "press" together.
I retro'd projectors and LEDs in to my housings and haven't have any issues with condensation. even drove through the heaviest rain storm i've ever been in a week or two after the mod and not one spec on water was inside the housings.
