Using the OLM Point Five Duckbill Trunk Spoiler is easy. First, if your car already has a spoiler, take it off. Then, clean the area where the new spoiler will go. Next, use the 3M double - sided adhesive that comes with the spoiler to stick it on. Make sure the temperature is over 60 degrees when you do this for the best hold. After installation, let it sit for 24 - 48 hours so the bond gets really strong. As for maintenance, just wash it regularly with a mild car cleaner. Avoid using abrasive materials that could scratch the paint. If you notice the spoiler is loose, check the adhesive and re - attach it if needed. That's all you need to do to keep your spoiler looking great and working well.
