What ever you do, do NOT try and use a spray tint product called "VHT Night Shades", unless you understand that you won't be able to look through it.
It's what people use to tint their tail lights. I had a buddy convince me to use it on my '08 stock shield. It tinted it alright! You could see light through it and that's about it.
Here is a pic at my in-laws place. It is NOT photoshopped.

Having said that, I still love the look of the stock shield tinted.
