Do I need to paint each piece separately or can I install first and paint later?

You can install first and paint after, but many builders prefer to paint panels off the car for better coverage and finish quality. Either approach works — just make sure all seams and panel gaps are taped or sealed before spraying to avoid overspray inside the engine bay or interior.

Will I need seam sealer or gap filler between the kit pieces and the factory body?

Yes. FRP panels will have natural gaps where they meet the OEM body. Use a flexible seam sealer or gap-filling compound rated for automotive use to ensure clean lines and protect against water intrusion. Sand and finish the sealer to match your paint.

Does this kit come with mounting hardware, or do I need to source fasteners separately?

The kit includes the body panels only. You'll need to source your own fasteners — brackets, bolts, and clips — based on your mounting approach. Reference your vehicle's service manual or consult a body shop for the correct fastener spec and installation points.
