Just bought this Carbon Fiber skin protector for my Xbox 360 S off ebay, it's made by Skinomi - but the ebayer did not include the solution that's supposed to be used in the instructions. Now I've got a place I go to for my iPhone 4, they spray the solution on the front an back of the phone before applying the protectors - the back however (carbon fiber) does have a real sticky side to it so I'm wondering if the liquid spray solution would be less important for that piece compared to the clear front film that isn't so sticky. Anybody have their two cents?
