What to know

Know Before You Order

All painted parts are not returnable and are FINAL SALE.

Since this is a customized part, all orders are made to match your specific requirements, and cannot be sold again.

Inspect all parts before accepting delivery.

If you notice any damage, refuse the shipment—this is the only way we can file a claim. Accepted damaged shipments may incur shipping and restocking fees.

Aging paint & color matching consideration.

We match paint using OEM factory codes, but older vehicles present more challenges. Over time, sun exposure, oxidation, and previous repaints can significantly alter your car’s color.
