Do I need to paint each piece separately before installation?

Paint and cure each panel individually before bolting them on. This prevents overspray on the chassis and allows you to sand and wet-sand between coats without masking the vehicle. Assemble after all paint is fully hardened.

Will this kit require drilling or custom fabrication to fit?

The Sigma design matches factory mounting points, but always test-fit each piece on your vehicle before final fastening. Some bolt-hole alignment may require minor spacer shims depending on panel wear or previous modifications to your chassis.

How should I prep the FRP surface before primer and paint?

Sand the entire kit with progressive grits to remove the mold gloss, then wipe with a tack cloth. Any small voids or imperfections can be filled with polyester filler before final sanding. Follow your primer and paint manufacturer's surface prep guidelines for adhesion.
