Disclaimer

By placing an order, you acknowledge that you have read and understood the following disclaimer, and you agree to waive any claims for return, refund, or chargeback based on the points listed below. Production or shipping delays, as well as the known characteristics of wet carbon fiber, are not grounds for dispute.

- Wet carbon fiber is Real 3K 2x2 Twill Carbon Fiber, hand-finished over fiberglass, making it a cost-effective, but slightly heavier and less durable alternative to dry carbon.

- Average lifespan is 0.5–2 years depending on sun exposure and care. With perfect maintenance and storage, it may last much longer, even indefinitely.

- Fading, yellowing, or clear coat wear over time is expected for wet carbon fiber ONLY and not grounds for return.

- Production and shipping timelines are estimates (based on averages) and may vary due to UPS, DHL, or FedEx processing the order.

- Any of the above defects associated with Wet Carbon Fiber, or any Production/ Shipping delays are considered normal wear and tear, and are not valid grounds for refund/return/dispute/chargeback.

Are Our Products Real Carbon Fiber?

Yes, all carbon fiber items listed for sale on Carbon Powered are made from genuine 3K 2x2 twill carbon fiber.
