Will these interfere with jack point access?

Check your vehicle's jack point location on the rocker before installation. Most side skirts are designed to sit above the OEM lift points, but verify clearance on your specific vehicle. If the jack point sits directly beneath the skirt area, you may need to trim or notch the panel for service access.

Do I need to sand and prime before painting?

Yes. Sand the entire surface with appropriate grit to remove any mold release agent, then apply your chosen primer and topcoat system. The raw FRP condition means the surface is prepared for adhesion — it is not pre-primed.

What's the best way to secure these to the vehicle?

FRP side skirts can be mounted using adhesive, fasteners, or a combination of both. Review your vehicle's rocker panel and door jamb area to determine which mounting method suits your setup. Fastener holes may need to be drilled depending on your preferred attachment method.
