A few years ago, redditor /u/flashtone experienced a hailstorm that damaged his car. It appears that the plastic coating held even when the glass did not, thus keeping the ice from completely penetrating the barrier and damaging the interior.
Some redditors are making off-color jokes about other protective coatings preventing other types of fluids from leaking. Others are pointing out that the car now has, as a feature, a decorative chandelier or mirrored disco ball.
