Will this interfere with my trunk seal or bumper panel?

The two-piece design mounts to the underside of the front bumper and does not affect trunk sealing. Check that your bumper mounting points align before assembly — minor gaps between pieces are normal and can be sealed with automotive-grade adhesive or filler once painted.

Should I glue the two pieces together or bolt them separately?

Both methods work. Adhesive creates a seamless appearance after paint; bolting allows future removal without damage. Whichever you choose, ensure both pieces are primed and sanded before assembly so seams remain clean once finished.

How do I prep this for paint?

Sand and prep the surface with your preferred grit before applying your chosen basecoat and clear. FRP gelcoat is UV-resistant, so it holds primer well and accepts most automotive paints without additional sealing.
