Will this fit if my bumper has sensor holes or fog light cutouts?

This trim is designed around factory mounting geometry. If your bumper has been cut for aftermarket fog lights or sensors, test-fit this piece before committing — you may need to trim or relocate the cutout depending on your specific modifications.

Do I need to prep or paint this before installation?

This comes in chrome finish ready to bolt on. No prep required unless you prefer a different color — in that case, sand lightly and use standard automotive paint protocols.

What fastens it to the bumper?

Mounting method not specified in the product data — test-fit against your bumper to confirm attachment style before ordering fasteners or adhesive.
