Will this interfere with the trunk seal or bumper cutout?

The Alpine profile is designed to sit cleanly within the OEM bumper opening without contacting the trunk seal. Verify alignment before final fastening to confirm clearance with your vehicle's specific configuration.

Do I need to drill new mounting holes?

No. This lip uses factory mounting points, so no drilling is required. Installation uses existing attachment locations on the front bumper assembly.

How should I prep the FRP before painting?

Sand the surface with appropriate grit to promote adhesion, then clean thoroughly before applying your chosen basecoat and clearcoat. Follow your paint manufacturer's specifications for surface prep and application.
