Will this interfere with my trunk when it opens?

No. The CVX lip is designed to sit below the bumper line and does not extend into the trunk seal area. Verify clearance by dry-fitting the piece before final adhesive or fastener application.

Should I use adhesive or drill-through fasteners?

Both methods work. Adhesive keeps the look factory-clean and requires surface prep; fasteners offer mechanical security and adjustability. Choose based on your preference for permanence and finish visibility. Sand and prep the surface before applying your chosen installation method.

What prep work do I need before painting?

Sand the primer surface to promote adhesion, then wipe clean of dust. The FRP is ready to accept your chosen primer and topcoat without additional sealing or etching steps.
