Will this interfere with the trunk seal or bumper fitment?

No. The Motox profile is designed to sit cleanly below the existing bumper line without contact. Verify clearance on your vehicle before final fastening, as bumper alignment varies slightly by year.

Should I use adhesive or drill through the mounting points?

This lip is designed for bolt-on installation at existing factory holes. Adhesive alone is not recommended for carbon fiber under load. Use fasteners at the mounting points and consider a small amount of urethane sealant around the base to prevent water ingress if desired.

What finish prep should I do before installation?

Sand and prep the surface where it meets the bumper to remove any mold release residue, then install. Most buyers apply their own clear coat over the carbon before or after mounting to protect against UV and maintain the finish over time.
