Can I paint each piece separately or does the full kit need to be painted as one unit?

Each piece can be painted independently. Sand and prep all four panels before painting, and you can coat them individually on sawhorses or stands. This gives you flexibility if you're staggering the build or working one section at a time.

What surfaces do I need to prep before primer and paint?

Sand the surface thoroughly with appropriate grit to open the gelcoat, then wipe clean. Fill any imperfections with body filler if needed before applying your primer and topcoat systems. Proper prep ensures paint adhesion and a clean final finish.

Do I need any seam tape or gap filler between the body kit pieces and the OEM panels?

Gap filler and seam tape are not included with this kit. Depending on your fitment, you may need adhesive or filler to blend the seams — verify the gaps once you mock up the pieces on your vehicle, then source materials accordingly.
