Will this guard fit over my current front bumper, or does the bumper need to come off?

The guard mounts at factory bumper points — your stock bumper stays in place. No removal needed, though you may want to check clearance with any aftermarket lighting or accessories already installed.

Does the chrome finish come pre-applied, or do I need to polish it after install?

Chrome plating is applied at the factory. Out of the box it's ready to bolt on. A wash and dry before installation is all you need.

What hardware is required to mount this, and is it included?

Mounting method and hardware are not specified — test-fit the guard first to confirm which fasteners work best with your bumper configuration before committing to install.
