Will these skirts block access to my factory jack points?

No. The C-2 profile is designed to work with stock rocker geometry. Before final installation, test your jack point access by placing your floor jack in its normal location—the skirts will sit above the lift point and won't interfere with standard jacking.

Do I need to adhesive-bond these or can I bolt them on?

These are designed for bolt-on installation using your vehicle's existing rocker-line mounting points. Fasteners are not included; source hardware rated for your panel thickness based on the vehicle's OEM fastener specification.

What should I use to prep these before painting?

Sand the surface with appropriate grit to accept your chosen topcoat, then wipe clean before paint application. Follow your paint manufacturer's surface prep guidelines for FRP—this ensures maximum adhesion and finish quality.
