Will these skirts block access to the jack points?

No. Verify jack point locations on your vehicle's undercarriage before final installation. Most side skirts are designed to clear factory lift points — mark and test the fit first, then drill access holes if needed based on your specific setup.

Do I need to drill holes to mount these, or are they bolt-on?

The FRP panels are designed for direct mounting to the rocker line. Reference your OEM panel attachment points and mount hardware to determine your fastening method — bolt-on to existing holes or drill new points as required by your installation plan.

Should I paint these before or after installation?

Paint before installation. The surface accepts base coat and clear coat without additional prep. Install once cured. This protects the seams and edges during fitment and gives a professional, seamless finish.
