Will the lip interfere with my trunk seal or rear panel gap?

No. This is a front-mounted lip designed to sit beneath the air dam at the front bumper. It does not extend rearward into the door or trunk area and will not affect rear panel fitment or sealing.

What should I do to prepare the surface before painting?

Sand and prep the surface lightly to ensure paint adhesion, then apply your chosen primer and finish. The FRP ships ready for this process — no additional grinding or sealing is required before you begin.

Can I install this without drilling new holes?

Yes. The lip utilizes factory mounting points, so installation relies on existing holes and attachment points at the air dam. Verify your vehicle's factory anchor locations before beginning work.
