INSTALLATION Step 1:Clean the area thoroughly with rubbing alcohol. Do not use Windex or similar products because it will leave a residue behind that will prevent the decal from adhering well. Step 2:Place the sticker in the desired location. Put a piece of masking tape down the center of the sticker to hold it in place. Step 3:Lift one half of the sticker up and peel off the white paper backing. Hold the sticker away from the paper backing taunt but be careful not to pull the masking tape off. Cut the Peeled paper backing off. Step 4:Slowly lower the sticker by rubbing it in place with a felt squeegee or a credit card wrapped in a sock. Start at the middle and then work your way out to the edges. Step 5:Fold the remaining half back and remove the paper backing. Slowly lower the sticker by rubbing it with the felt squeegee or sock covered credit card. Start at the middle and work to outer edges. Step 6:For best results do not apply a sticker in extreme hot or cold temperatures. Step 7:Use a pin to poke any air bubbles in the center and push the air out through the hole.
