Will this lip interfere with my bumper or factory trim when installed?

No. This piece is designed to mount below the bumper using factory attachment points. Verify your vehicle's mounting holes are clear of debris or corrosion before bolting down, and ensure no aftermarket bumper extensions occupy the same area.

Should I use adhesive or bolt this down?

This lip is engineered for bolt-through installation at factory mounting locations. Bolts provide the most stable connection at highway speeds and are the recommended method. Adhesive-only mounting is not recommended for front-facing aerodynamic pieces subject to wind pressure.

What prep work do I need to do before painting?

Sand the primer surface with standard automotive sandpaper and wipe clean to remove dust. Mask off any areas you don't want painted, then apply your chosen primer and topcoat according to paint manufacturer instructions.
