Aluminum panel set for attaching to fuel lids. This is a set of 2 aluminum panels and 1 real carbon sheet (black). The size is specifically designed for the vehicle, so it fits perfectly. Made of thin aluminum plate and flexible carbon so it can be fitted even if the fuel lid has curved surfaces. Attaches to the fuel lid with double sided tape and is pre-attached to the back. Made of 0.01 inch (0.3 mm) thick aluminum plate with a hairline finish. We do not have surface treatment such as anodized aluminum products. (As a result of 3 years of use in outdoor parked vehicles, slight deterioration has been seen, but there was no severe corrosion or rust. The rivets are dummy, but they are drilled into the aluminum panel and then inlaid into the glue. For Mazda CX-3DK series (DKEFW/DKEAW/DK5FW/DK5AW/DK8FW/DK8AW) *This product is made after the order is received, so it takes about 10 to 14 days to ship the product.
