Will this cover work over my factory bumper sensors?

Test-fit before final installation — chrome covers can obscure or deflect sensor signals depending on mounting depth. You may need to route around sensor housings or remove the cover panel in those areas to maintain sensor function.

Does this bolt to the bumper beam or the lower valance?

Mounting method is designed for factory attachment points. Confirm your specific mounting hardware against your vehicle's service manual, as attachment varies by trim level and bumper assembly.

Should I paint this before installing?

Not necessary — this ships with a chrome finish ready to bolt on. If you want a different finish, handle painting before mounting to avoid overspray onto the bumper beam.
