Can anybody w/ prior experience w/ this product share some experiences w/ installation? Is it wet or dry? Easy? How does the Crystal Skin hold up over time? I've got mine pre-ordered based on some feedback on this forum (I'm hesitant to put my IS on the front of my iPhone 4 b/c of the orange peel look), but the product doesn't seem to have the following that IS or Wrapsol has. ????
