Do I paint each piece separately or after installation?

Paint each piece before final installation. This gives you full access to all surfaces and eliminates masking around mounted panels. Easier to achieve even color and gloss across the whole kit.

Will the side skirts interfere with jack points on my vehicle?

Verify the location of your OEM jack points before installation. If your jack points sit lower or inboard, the side skirts will clear them. If you use a floor jack, placement on the reinforced rocker area behind the skirt is standard practice.

What should I use to gap-fill the seams between pieces?

Flexible body filler or FRP-compatible seam tape bridges gaps between panels. Sand and prime all seams the same as the rest of the kit before final paint. This ensures a seamless finish and prevents water infiltration at the joints.
