Do I need to sand and prime each piece separately, or can I prep the whole kit at once?

You can prep all seven pieces at once. Sand the entire kit with appropriate grit to open the FRP surface, then apply your chosen primer system across all components before final paint. This ensures consistent finish and cure time across the full body kit.

Will I need gap filler or seam tape where the side skirts meet the rocker panels?

Some buyers use flexible seam sealer at panel seams for a factory-flush appearance. Whether you need it depends on your fitment tolerance and desired finish quality. Test-fit the kit to your vehicle first, then decide if sealing or filler improves the gaps to your standard.

Can I install this wide body kit myself with basic hand tools?

Installation requires familiarity with panel alignment, fastener placement, and your vehicle's existing mounting points. Review your vehicle's service manual for OEM fastener locations, and verify factory mounting points on your specific chassis before starting. Many builders handle this themselves; some prefer professional fitment to ensure panel alignment and finish quality.
