yea but if you do OUTSIDE then it has to be a sticker or ull eventually lose it...
if its inside its protected from elements and such, and if it ever falls off u can just reapply

those rubber/plastic things work nice like that
I'd be proud to plant one on my baby as long as its not there forever and gets the paint all horrid

or window all sticky like
Edit: Only have 2 stickers on my car one boasting my Eibach springs and the other is on the passenger side bottom left hand portion of the window
its about 1" by 1" saying "If you don't clean it, don't touch it" with a red stop sign
