Do I need hood pins to secure this scoop, or will fasteners alone hold it?

This scoop is designed for bolt-down installation using fasteners at its mounting perimeter. Hood pins are not required unless your setup involves a modified or heavily vented hood that benefits from additional retention—that call depends on your specific build and drive style.

Will this scoop work on a roof, or is it hood-only?

The universal sizing and profile work on both hoods and roofs. Your mounting points and panel contour will determine the best fit. Measure your intended surface and compare it to the 26" × 25" footprint before committing to placement.

What prep work does the FRP need before painting?

Sand and prep the surface with standard automotive prep techniques before applying your chosen base coat and clear. The exact grit and primer type depend on your paint system, so follow your paint supplier's recommendations for best adhesion.
