Will this bumper cover align with my lower valance and existing trim?

The bumper uses factory mounting points, so it sits in the same position as OEM. Before final install, verify that any aftermarket lower valance or air dam you've added clears the new bumper profile — measure the extension at the lowest point and test-fit if possible.

Does this cover have pre-drilled holes for fog lights or sensors?

The raw design ships smooth. If your bumper configuration includes fog light cutouts or parking sensor holes, you'll mark and cut those locations based on your vehicle's OEM hole pattern. Use your existing bumper or service manual as a reference for placement.

What prep work is needed before I paint this?

Sand the surface with appropriate grit to scuff for paint adhesion, then clean thoroughly to remove dust and oils. Your paint supplier can recommend the right primer and topcoat system for FRP — always follow their prep guidelines for best results.
