First of all, I apologize for the stupid question, but for the life of me I can't figure out this issue.
Anyway, I'm a bit of an eBay junkie, so I'm constantly looking on there for cool new stuff to put on my car. Once I found someone selling their entire collection of audio and performance stickers! I also have some of the brake caliper covers (red, of course) and some kickass precut tint. All I had to do was put it on the windows

Oh, and can't forget the set of interior lights (they cycle through 7 colors) and the LED side mirrors.
But back to the question: I went to put some of the stickers on my car the other day, and I can't get them to stick! I've tried everything, but they just keep peeling off. Could I have done something wrong when I spray painted the car gold, or am I missing a step to putting stickers on a car?
Thanks for the help!
