I luckyly found out this topic. Similar to the work above, i have done the same thing to my lovely BMW X1 and almost every single person who saw it, loved it.
Its the same process. After removing four screws on top of the bumper, i relased the 8-9 clips that hold the kidney grill. And then i started to do it myself.
So that is the result. I uploaded the photos of it. It has been 3-4 months since this application. And there was no peel off or anykind, still same lovely bright colors, still same lovely looking.
I just wanted to show you all guys. I hope you'll like it as well.
