Do these skirts block access to the jack points?

No. Ghost-style skirts are designed to sit proud of the rocker line and work around factory jack locations. Verify clearance on your specific vehicle before installation, but standard placement preserves OEM jack point access.

What do I need to do before painting?

Sand the surface with standard automotive sandpaper and wipe clean. Apply a quality automotive primer and topcoat per your paint system's instructions. The FRP surface accepts paint and clear coat without additional bonding agents.

What fastening hardware comes with these?

The skirt set includes the FRP panels only. You'll need to source fasteners and brackets that match your vehicle's factory rocker anchor points. Your dealer parts diagram or service manual will specify the correct hardware for this fitment.
