Will this interfere with my trunk seal or undercarriage?

No — the Alpine profile is designed to sit flush with the factory bumper line. Verify clearance with your existing trim and any aftermarket front-end components before final installation.

Can I use adhesive, or do I need to drill?

This lip uses factory mounting points, so fastener installation is recommended for durability and security. Adhesive-only mounting is not advised for highway use.

What prep is required before paint?

Sand and prep the surface thoroughly before applying your chosen primer and finish. The FRP is stable and holds detail well once properly prepped and sealed.
