I found the answer... It's called Fw1 Racing formula (High Performance Cleaning Wax).
I had bought it at a gas station a while back. It works great on the paint. I tried everything I could think of.
Just remove the tint with a razor blade and leave the glue (no worries).
spay on the FW1 and wait 2 minutes. Use a razor blade to remove the glue. You won't need any elbow grease. It cleans the window to a shine as you go. A simple wipe down with a paper towel and you're finished.
