Do these need hardware to install, or do they use factory bolt holes?

These mount at factory rocker points — use your vehicle's existing mounting hardware. Confirm bolt size and torque spec in your service manual before tightening.

Will the anti-slip coating wear off with regular use?

The textured finish is built into the panel construction and is designed to withstand boot traffic, mud, and weather. Normal wear will occur over time; touch-ups are possible with sandpaper and a matching finish applied by you.

Can I paint over these if I want a color match?

Surface prep and paint are your call — sand lightly to ensure adhesion, then apply primer and paint to match your vehicle. The anti-slip texture will remain underneath.
