The spray is VHT Nightshade. I have my 3rd brake light on my Denali smoked out with it. I will get some pictures of members cars from a different forum (Tahoe's and Denali's) who have tinted their lights in different shades for you to see.
BTW, if you are in SoCal, there is a guy who owns a shop and deals with GM, Range rover, and BMW accessories. He has tinted many lights and does a good job . If you are interested in his info, let me know.
Here is a light tint on the store owners Tahoe. I will get more pictures up soon. Let em know how dark you want to see.
