Will these skirts block access to my jack points?

Sigma side skirts are designed to clear factory jack point locations on the rocker. Verify your vehicle's OEM service jack access before final installation — if your manual specifies a specific lift point geometry, test fit that area first to confirm clearance.

Do I need to sand and prime before painting?

Yes. Sand the surface with appropriate grit to open the surface, then apply your chosen primer and topcoat system. The FRP arrives in a sealed state ready for this prep work — no stripping or additional surface work is needed.

Are these glued on or bolted?

Installation method depends on your preferred fitment approach. Many builders use a combination of adhesive and fasteners through existing rocker mounting locations. Reference your vehicle's service manual for OEM mounting hole locations and verify the skirt panel alignment before committing to either method.
