If the adhesive is on the logo itself u put the sticker inside of the window, if it is a standard sticker( the adhesive is on the back of the logo ) u put it on the outside of the window.
it was a pain in the @ss trying to get it to stick to my ice cold window.. it stuck to the backing stronger to the window.. but i got it on!..... just advice for future sticker installs.... do it on a warm window.... lol
