Will this interfere with the trunk seal or bumper fitment?

The two-piece design mounts to the factory bumper attachment points, so fitment follows OEM geometry. Verify clearance between the lip edges and your vehicle's existing body lines before final fastening. Any gaps can be sealed with flexible trim adhesive if needed.

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

The factory mounting points are bolt-on — no drilling required. Use the OEM fastener locations on your bumper for a clean, removable install. Adhesive alone is not recommended for sustained vibration loads at speed.

How should I prep the surface before painting?

Sand the surface with automotive-grade sandpaper and wipe clean before applying your chosen base coat and clear. Standard automotive prep — no special treatment needed for FRP.
