Does this kit come with all four pieces ready to bolt on?

Yes — the kit includes all four pieces complete. You'll need to prep and finish them before installation, but there are no missing components in the set.

Can I paint each piece separately before install, or should I install first?

Painting before installation is ideal — it gives you cleaner coverage and easier access to all surfaces. Just mask off mounting tabs and surfaces that will contact the body during fitment to keep glue and fasteners from interfering with your finish.

What prep work does FRP need before painting?

Sand the surface to an even texture and remove any mold release residue with a degreaser. Once clean and dry, apply your primer and paint system of choice — FRP accepts most standard automotive finishes without issue.
