Do I need to sand these before painting?

Yes. Sand the surface with appropriate grit to promote paint adhesion, then wipe clean before applying your chosen base coat and clear. The factory primer provides a foundation — surface prep ensures your finish bonds properly.

Will these panels affect my jack point access?

Check your vehicle's jack point locations before final installation. These side skirts extend the rocker line; verify clearance with your OEM or aftermarket jack lift points to avoid interference during service.

What fastening method should I use?

Mounting hardware is not included with these panels. Consult your vehicle's service manual or a professional installer to identify the correct fastener type and torque specifications for your specific rocker and frame mounting points.
