Will this cover my existing bumper or do I need to replace the core?

This is a cover that installs over your factory bumper structure. Your OEM bumper frame and reinforcement stay in place; the cover simply replaces the aesthetic panel. Verify that your current bumper core is straight and secure before installation.

Does this cover sensor holes or do I need to drill them out?

Reference your vehicle's OEM bumper location for any existing sensor or parking-aid holes before finalizing installation. If your setup requires cutouts, mark and drill them after the cover is test-fit to ensure precision alignment.

How should I prep the surface before paint?

Sand and prep the surface with appropriate abrasives to achieve a smooth base. Follow your paint system's prep instructions for primer adhesion. Proper surface prep is critical for color match and durability.
