Can I paint each piece separately before installation, or should I paint it all together?

Paint each piece separately before final assembly. This gives you better coverage on all edges and prevents overspray on adjoining panels. Sand and prep the surface thoroughly before applying your chosen primer and topcoat.

Do I need gap filler or seam tape where the pieces meet?

Gap filler or flexible seam tape is recommended where the side skirts meet the front and rear bumper covers to ensure a clean transition and protect against debris. The kit itself does not include sealing material — source based on your preferred finish and fitment tolerance.

Is this a full replacement or does it integrate with factory body lines?

The bumper covers and side skirts are designed to work with factory body lines and factory mounting points. Verify your vehicle's existing fastener locations and panel gaps before committing to fastener type or adhesive method.
