Using your Seibon dry carbon fiber replacement roof is straightforward. Just have it installed by a professional for the best fit. When it comes to maintenance, since these dry carbon products don't have UV protection, it's important to take steps to protect them. If you're not painting or wrapping the roof, coat it with an automotive - grade clear coat that has UV inhibitors. This will help prevent damage from the sun. During shipping, be aware that most Seibon products are shipped via Pilot Freight Services. In - stock items take about 1.5 - 2 weeks to be packed and shipped. Always inspect your delivery carefully. If you notice any damage during transit, contact us right away. And remember, most items are made to order, so expect a wait of 8 - 12 weeks if you pre - order, but it'll be worth it for this high - quality product.
