Will this lip interfere with the trunk seal or lower bumper panel?

No. This lip mounts to the existing front bumper mounting points and does not extend into the bumper seam or trunk area. Confirm your vehicle's OEM bumper attachment holes align with the lip's factory mounting bosses before final assembly.

Can I install this using factory fasteners, or do I need new hardware?

This design uses factory mounting points, so your existing hardware should work. Always verify bolt sizes and condition before installation—replace any rusted or stripped fasteners with new hardware rated for outdoor use.

What prep work should I do before painting?

Sand the surface with appropriate grit to create a smooth base, then wipe clean to remove all dust. Use a quality filler primer if you find any minor voids, and finish with your chosen topcoat system.
