Will this interfere with the trunk seal or bumper attachment points?

No. This lip is engineered to sit forward of the existing bumper and does not contact the trunk weatherstripping or mounting brackets. Verify clearance by dry-fitting against your vehicle's front bumper assembly before bonding.

Should I use adhesive or drill through the bumper to secure it?

Adhesive bonding is the standard method for FRP lips on this platform. Surface prep is critical — sand and clean the mounting surface thoroughly before applying a quality automotive adhesive rated for plastic-to-plastic or plastic-to-metal bonds. Consult your adhesive manufacturer's application guide for cure time and clamp pressure.

How do I prepare the FRP for painting?

Sand the surface with progressively finer grits to smooth the factory finish, then wipe with a tack cloth to remove dust. Apply your chosen primer, primer-surfacer, or base coat per the paint manufacturer's instructions. The FRP accepts standard automotive primers and finishes without additional treatment.
