Will this bolt to my existing bumper cover or do I need a new cover too?

This bracket works with your current bumper cover as long as it's in good shape. If your cover is cracked, warped, or heavily damaged, replacing the bracket alone won't fix poor fitment — you'd need the cover addressed first.

Do I need fasteners or hardware to install this?

Mounting hardware is not included with this bracket. You'll need to source fasteners that match your vehicle's factory mounting points — check your service manual or test-fit against the holes before ordering hardware separately.

Can I paint this bracket or does it need primer?

The bracket comes ready for paint or primer application. Clean and degrease the surface, apply your choice of primer and paint, and allow full cure time before installing — this prevents chipping where it contacts the cover or frame.
