Will this fit the factory bumper reinforcement bar underneath?

This is a cover only — it mounts to the existing bumper structure. Verify clearance with your reinforcement bar before final assembly, as fitment can vary based on prior damage or modifications to the frame.

Does this cover the factory sensor holes and trim openings?

The AF-4 profile is designed to match OEM opening positions. Dry-fit before painting to confirm your sensors and trim pieces align with the cover's cutouts — some minor adjustment to mounting points may be needed depending on your specific vehicle history.

What prep is needed before I paint this?

Sand and prep the surface per your chosen paint system's requirements — polyurethane takes most finishes well. Apply your color, then clear coat for protection and durability. Refer to your paint manufacturer's guide for cure times and application steps.
