Will this fit if I've already modified my front bumper or lower valance?

This molding is designed around factory geometry and mounting points. Any significant bumper modification, sensor relocation, or valance work will require test-fitting before final commitment. Confirm your bumper layout matches stock configuration.

Does this come with hardware, or do I need fasteners?

Hardware is not included. You'll need to source fasteners compatible with your existing factory mounting points—typically clips or bolts already present on your valance frame.

What surface prep do I need before painting?

The primed finish is ready to scuff with fine grit sandpaper and accept your topcoat directly. Refer to your paint manufacturer's guidelines for primer compatibility and drying times before color application.
