Do I need to paint each piece separately before installing?

Yes. Sand and prep the FRP surface per your chosen paint system, then apply primer and finish. Paint each piece before final assembly for even coverage and easier handling. Your paint supplier can recommend surface prep based on your specific topcoat.

Will the side skirts interfere with my jack points?

The side skirts are designed with factory mounting points in mind, but verify clearance with your vehicle's OEM jack location before final installation. If needed, you can adjust the skirt mounting height slightly during fitment to preserve access to service points.

Does the four-piece kit include any gap filler or trim tape for seams?

No. The kit includes the four body panels only. Seams between panels are fitted to factory gaps. You may want to source trim tape or weatherstripping separately if you prefer a sealed edge where pieces meet the chassis.
