Will this lip interfere with my bumper or trunk at full compression?

The EVS lip extends downward from the bumper fascia. Verify clearance with your OEM bumper attachment points and suspension geometry before finalizing mounting locations. If you run lowered suspension, test the lip height at full droop on a lift or with a helper—do not assume factory ride height.

Should I adhesive-bond this or drill through the bumper to mount it?

FRP works well with both adhesive and mechanical fasteners, depending on your comfort level. Adhesive keeps the bumper unpierced but requires careful surface prep and cure time. Drilling allows for adjustability and future removal without residue. Choose based on your bumper's material—check whether your OEM bumper is plastic or composite before selecting fasteners or epoxy.

How much prep work is required before painting?

Sand the surface to remove any mold release and create tooth for your primer. A 220–400 grit progression works well, but follow your primer manufacturer's recommendation for grit specification. Once smooth, wipe down with a tack cloth and apply your chosen primer and topcoat system.
