Using this antenna cover is easy. First, make sure your car is one of the compatible models: 2022 - 2025 Subaru WRX, 2022 - 2025 Subaru BRZ, or 2022 - 2024 Toyota GR86. When it comes to installation, pick a day with a temperature between 75 - 95 degrees and try to keep this temperature for at least 24 hours. It's even better if you can maintain it for 72 hours to get the best bond. Before installing, clean the area where you'll put the cover to get rid of dirt, debris, and Armor All. Test - fit the cover to see how it goes. Once you're satisfied, remove the backing from the double - sided adhesive and stick the cover on. Apply firm and even pressure for 30 seconds. As for maintenance, just keep it clean with a regular car cleaner. Avoid using abrasive materials that could scratch the high - gloss carbon fiber finish. That way, your antenna cover will stay looking great and stylish on your car.
