So I had the flu and then I was just lazy, but I made it out to the garage last night to tinker a bit. Put the speaker grilles in the dash (semi-gloss black doesn't match the flat dash - but for now whatever), and then I popped off the 3rd brake light and cleaned it up, popped out the package tray/speaker cover and cleaned it up too... and then I turned my attention to the peeling purple tint. I started with a heat gun and pulled off the remaining layer - and I figured I was done. As I was trying to wipe of the remaining adhesive with solvent I came to realize there was a second layer! FML. Heat gun didn't work this time. So I went inside to ask my wife for the clothes steamer... She was so offended that you'd think I asked to bang her sister (again)?!
Anyway, it worked like a very painful charm until I ran out of water and patience. I'll finish it tonight.
