Can I paint each piece separately before installation?

Yes. The individual components arrive as separate pieces, so you can mask, sand, and finish them off-vehicle. This approach often yields cleaner results and avoids overspray on surrounding trim. Paint in a well-ventilated space and allow full cure time between coats before assembly.

Do I need gap filler or seam tape between the panels and my OEM body?

Gap management depends on how precisely the pieces align with your specific vehicle. After a test-fit, use adhesive-backed foam tape or automotive-grade sealant to close any irregular gaps. This protects against water ingress and gives the install a finished appearance.

What fastening method should I use to secure these parts?

Reference your vehicle's OEM body panel mounting locations and fastener patterns. Most builders use a combination of self-tapping fasteners, rivnuts, or adhesive compound suited to FRP. Verify clearance around sensors and existing hardware before drilling or bonding.
