Will this interfere with my bumper trim or trunk seals?

No. This lip mounts to the lower bumper section below the main body line, clear of seals and trim. Verify your bumper has not been previously modified before installation — factory configuration provides proper clearance.

What installation method does this use — adhesive or bolts?

This lip is designed for bolt-on installation using the factory bumper fastener points. No drilling required. Hardware fasteners are not included — use stainless steel bolts matched to your bumper's existing hole pattern and your vehicle's service specifications.

How do I prep the FRP before painting?

Sand the surface with medium-grit sandpaper to promote paint adhesion, then wipe clean. Apply your chosen primer and finish coat per the paint manufacturer's instructions. The FRP surface is stable at highway speeds once properly finished and secured.
