Do I need to paint each piece separately or as an assembled kit?

You can paint the pieces before or after installation — your call. If you're prepping in a paint booth, painting them individually gives you access to all surfaces and seams. If you prefer to assemble first, ensure you leave mounting points and fastener areas unmasked so they bond properly during installation.

Are the side skirts going to interfere with jack point access?

Side skirts sit below the rocker line. Before final assembly, verify your vehicle's jack points against the skirt placement using your service manual or OEM jack location diagram. Minor trimming at the jack access point is straightforward with a rotary tool if needed.

What should I use to fill gaps between the kit pieces and the OEM body?

Gap filler and seam tape designed for automotive FRP work best — brands like 3M Scotch-Weld and polyurethane gap sealers are common choices. Apply filler after final alignment and before primer. Sand smooth, then prime and paint over the seams for a seamless finish.
