High Quality Vinyl Decal Adhesive sticker. These stickers are designed for the outside of a vehicle window (adhesive is on the back) This decal DOES NOT have a white outline, the only white is Mr Pool's Eyes! Looks Great on a side or rear window! Installation Instructions!!! PLEASE READ 1. Prepare the surface!!! This is your most important step! Your decal will adhere best to a smooth, clean surface! Rubbing Alcohol is best to clean the area with. Please do not use Windex or other glass cleaners (you can use them BEFORE the alcohol if your window is really dirty) as these cleaners leave a residue behind. Tip: avoid applying your decal in extremely hot or extremely cold environments. 2. Carefully peel and stick one edge of your decal ensuring that the location is correct and that your decal is level. Then slowly smooth the rest of the decal down Tip: I like to use a credit card or hotel room key etc to smooth down the decal, you can cover it with a paper towel or mirofiber cleaning cloth to prevent marring the decal
