Do I need to sand and prep these pieces before painting?

Yes. Sand the surface with appropriate grit before applying your chosen base coat and clear. This ensures proper paint adhesion and a clean finish across all four pieces.

Can I install this kit piece-by-piece, or do I need to remove everything at once?

You can install pieces individually — the front bumper, side skirts, and rear bumper are separate assemblies. This gives you flexibility to work on one section at a time if preferred. Reference your vehicle's mounting point locations before drilling or fastening.

What hardware do I need to mount the side skirts to my rocker panels?

Hardware is not included with this kit. Determine your mounting method (bolt-on, adhesive, or hybrid approach) and source fasteners appropriate for FRP-to-metal or FRP-to-plastic attachment. Consult a professional installer if you're unsure about drilling locations or load ratings.
