Will these interfere with jack point access?

No. These panels are designed to work around factory jack points. Before final installation, verify clearance between the panel edges and your vehicle's jack pad locations — your owner's manual identifies these spots.

What prep is needed before painting?

Sand and prep the surface with appropriate grit per your paint system's requirements, then apply primer and your chosen topcoat. Follow the paint manufacturer's instructions for adhesion and cure time on FRP substrates.

Do I need to modify the body or chassis to install these?

No. These panels attach to existing factory mounting points without drilling holes or structural modification. Use the bolt-hole locations as-is and torque fasteners per your vehicle's service manual specifications.
