Do I need to sand each piece separately before painting?

Yes. Sand the surface with fine-grit paper to create a smooth base for your paint system. This ensures even color lay and adhesion across all four panels. Wipe down with a tack cloth before priming or basecoat application.

What hardware do I need to install these pieces?

Verify the mounting points on each panel against your vehicle's factory bolt locations and existing fastener holes. You will need appropriate fasteners for secure attachment. Consult your vehicle's service manual or an experienced installer to confirm the correct fastener specification for your application.

Can I paint the pieces before or after installation?

Both approaches work. Pre-painting all four pieces ensures consistent coverage in a controlled environment and avoids overspray on the vehicle. Post-installation painting may be easier for gap blending. Choose based on your workspace and finishing skill level.
