Do these come with all the hardware needed for installation?

This set includes the front lips only. Before installing, check your vehicle's existing mounting point condition and have fasteners on hand that match your OEM setup — many builders source stainless hardware to complement FRP bodywork.

What should I do to prepare the FRP before painting?

Sand the surface and clean thoroughly before applying your chosen base coat and clear. The two-piece design means you can prep and paint each lip independently, which can make the process easier to manage in a home garage.

Since these are 2 pieces, can I install just one lip if I only need one side?

Yes — the two-piece configuration gives you that flexibility. Install either lip individually or as a complete set depending on your build plan and what your mounting points support.
