Will this interfere with the factory trunk seal or hood alignment?

No. This front lip sits at the lower fascia edge and does not contact hood or trunk components. Standard factory gaps remain unaffected during operation or opening/closing cycles.

Can I use adhesive instead of drilling, or do I need to drill through the fascia?

This panel is designed to use existing factory mounting holes on the front fascia. Verify hole alignment on your vehicle before final assembly. Adhesive-only mounting is not recommended for front lips; factory fastener points provide the security needed at highway speeds.

How do I prep the FRP before painting?

Sand the surface with appropriate grit to achieve your paint adhesion target, then clean thoroughly to remove dust and debris. Apply your chosen basecoat and clear coat system. Consult your paint supplier for recommended surface prep steps specific to your finish.
