tinting the 3rd brake light

Man how the hell do you get that thing off? I can't figure it out, and someone, I'm thinking you, did a DIY saying don't attempt because of possibly breaking something. I tinted everything but that, because I'm scared to attempt getting it off. But it looks retarded red now.

Yeah when I finally got it to pop off I broke a couple of the little plastic tabs that hold the assembly together. There's still a bunch more tabs keeping everything together but it bothers me to know that it's broken. You could mask around it and spray in place if you don't want to take it to a shop to have it removed.
