Will this interfere with my OEM front bumper trim or splash guards?

No. This lip is engineered to sit cleanly alongside the factory bumper. Before final installation, dry-fit and verify clearance with any existing trim pieces, especially lower diffuser sections. Minor adjustments to mounting bracket angle can accommodate most factory setups.

Should I drill mounting holes or use adhesive bonding?

This lip is designed for OEM mounting point installation, which typically involves bolting through factory holes in the bumper. Adhesive-only mounting is not recommended for front-end aero pieces due to vibration and wind load. Use the factory fastening locations and verify fastener clearance before assembly.

What prep work does FRP need before painting?

Sand the entire surface with fine-grit sandpaper to remove the glossy gelcoat, then wipe down thoroughly to remove all dust. A light coat of primer sealer before base coat will ensure even color coverage. Follow your paint manufacturer's surface prep guidelines for best results.
