Will these mount at the factory rocker points, or do I need to drill?

These use your CR-V's factory mounting locations — no drilling or welding required. Test-fit before final fastening to confirm alignment.

Do these come with mounting hardware?

The listing confirms the panels only. You'll need to source fasteners that match your vehicle's original attachment method — check your service manual or dealer parts diagram for the correct hardware.

Does aluminum need protection before I install it?

Aluminum resists rust on its own, but inspect the mounting surfaces and any bare edges before installation. If you want added durability, a clear coat or protective wrap is optional depending on your climate.
