Should I paint each piece separately before installation?

You can prep and paint all four panels before bolting them on, or install them first and paint as an assembled kit. Painting off the vehicle lets you work in a controlled space and catch every angle. If you choose post-install finishing, mask around fastener holes and seams carefully.

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

Panel gaps depend on your mounting accuracy and how tightly you torque the fasteners. Start with proper alignment and snug bolts — most builders don't need filler tape. If small gaps remain after installation, flexible urethane gap filler works well and blends under paint.

Can I install this myself with hand tools?

Yes. Locate the factory mounting points on your vehicle, align each panel, and bolt it down using basic wrenches or sockets. No drilling, welding, or specialty tools required. Take your time with fitment on the first two pieces; the rest will follow. A second set of hands makes alignment easier.
