Using this OLM Point Five Duckbill Trunk Spoiler is a breeze. First, check if your vehicle has an existing spoiler. If it does, take it off. Then, use a clean cloth to wipe the area where you'll put the new spoiler to make sure it's free of dirt and dust. Next, take the spoiler and apply it using the 3M double - sided adhesive that comes with it. Remember, the temperature should be over 60 degrees for installation to get the best bond. After installation, let it sit for 24 - 48 hours so the bond gets stronger. As for maintenance, you can wash it just like the rest of your car. Use a mild car wash soap and a soft sponge or cloth. Avoid using abrasive cleaners that could scratch the paint. Also, check the adhesive periodically to make sure it's still holding the spoiler firmly in place.
