Do these skirts block access to the factory jack points?

No. Confirm mounting point locations on your vehicle before installation and verify clearance around any service access points you use regularly. The rocker-mount design typically allows full jack point access, but your specific vehicle may vary — measure twice before drilling.

What prep work is needed before I paint these?

Sand and prep the surface to accept your chosen primer and topcoat. Since they ship in raw FRP condition, light scuffing ensures adhesion. Your local paint shop can advise on final surface preparation based on the finish system you plan to use.

Are installation fasteners included?

This set includes the skirts only. Source fasteners based on your vehicle's rocker mounting holes — most builders use stainless steel bolts and washers from their local hardware supplier to match the rocker attachment method. Refer to your vehicle's service manual for fastener specifications.
