Prepare the decal by firmly rubbing a credit card across the face of the decal. This ensures proper adhesion of the cover onto the decal allowing you to remove the backing easier.
Ensure you are working with a clean window surface. To clean the window DO NOT USE WINDEX. use soap and water to initially clean the surface and then wipe the surface down with rubbing alcohol.
Place the decal in the desired location with a piece of masking tape on the top of the decal to hold it in place.
Lift the decal up and peel the backing paper off the decal. Be careful not to pull the masking tape off. Be careful not to allow the adhesive side to touch, this can ruin the decal.
Slowly lower the decal and rub it in place with a credit card. Start closest to the masking tape. Firmly rub the sticker in place to make sure there is no air trapped under the sticker. If you find you have air bubbles, you can take a needle and poke a hole in the vinyl and use your credit card to push the air out.
For best results wait 24 hours then slowly peel the clear cover off at an angle. Be careful not to pull the sticker off the surface. If the sticker pulls away from the surface repeat step 5.
