Using your Seibon dry carbon fiber roof is straightforward. First, make sure your Subaru WRX or STI (2015 - 2021) is clean and ready for installation. When installing, follow the manufacturer's guidelines carefully. For maintenance, keep in mind that the dry carbon finish is matte and lacks UV protection. If you don't plan to paint or wrap the roof, apply an automotive - grade clear coat with UV inhibitors as soon as possible to protect it from the sun. After that, regular car washes with mild soap and water will keep it looking great. When receiving the shipment, take the time to inspect it thoroughly. If you notice any damage during transit, let us know right away. Remember, most of these roofs are made to order, so if you pre - order, be patient as it can take 8 - 12 weeks to arrive.
