Will this interfere with the factory bumper seal or trim panels?

No. The HM-S profile is engineered to sit within OEM bumper boundaries. Before final installation, dry-fit the assembly and verify clearance around existing trim and sensor cutouts on your specific vehicle.

Should I drill mounting holes or use adhesive-backed attachment?

The air dam is designed to use your vehicle's factory mounting points, which are typically bolt-through locations on the bumper beam. Avoid adhesive-only installation on FRP pieces carrying aerodynamic load — fastener retention ensures stability at speed and under cornering forces.

Can I apply paint directly to the primer, or does the surface need additional prep?

Sand the surface with 220-grit or finer to ensure proper paint adhesion. Wipe clean of dust, apply your chosen primer or base coat per the paint manufacturer's instructions, and finish with color coat and clear. Proper surface prep is the foundation for a long-lasting finish.
