I stopped by David's shop last week so he could remeasure/cut the center tail light tint strips since the file didn't save properly.
The vinyl is quality material, and the opacity is just enough to appear black not on direct sunlight. Overall, David has a great setup and his shot is top notch. Great guy and definitely looking forward to doing business in the future.

Comparison during installation/test fitting

Overall I love the additional detail they add to the car. With Deep Impact Blue being a darker blue, I think the tint helps to tie together the rear tail lights/black trunk panel more by eliminating the "in your face" LED boards.
