Do I need fasteners to bolt this on?

The panel bolts at factory points, so you'll need OEM bolts or equivalents. Hardware is not included — source bolts that match your vehicle's original spec before installation.

What prep work is needed before painting?

This arrives as bare panel. Light surface prep with fine grit sandpaper, then primer and paint per your chosen system. Exact grit and primer type depend on your paint prep method — refer to your paint supplier's recommendations.

Can I bolt this straight on without welding?

Yes — it mounts at factory rocker and door jamb points with bolts only. No cutting, welding, or drilling required.
