Will this interfere with the trunk or hood seal when installed?

No. This spoiler attaches to the lower front bumper and does not contact the trunk or hood. Verify clearance with your bumper and any factory sensors before final installation.

Should I use adhesive or fasteners to mount this?

Fastener mounting is recommended for long-term durability and easy removal. Use corrosion-resistant hardware and torque to the vehicle service manual specification. If you prefer adhesive, ensure the surface is clean, dry, and properly roughened for maximum bond.

How should I prep this for paint?

Sand the surface with progressively finer grits to create a key for primer adhesion. Clean thoroughly to remove dust and oils. Apply primer, then your chosen topcoat. A clear coat finish is recommended to protect against UV exposure and enhance durability.
