Michael: (voiceover) There are a couple of ways to make a vehicle bullet resistant. Sixty thousand dollars worth of titanium siding will do the job. Or you can pick up a couple extra copies of the yellow pages from your local phone company. Most non-armor-piercing bullets will only penetrate a phone book to a depth of an inch or two. Behind a layer of steel, it's more like a quarter of an inch. Commercially available foam sealants will keep your tires rolling long enough to get you out of danger. For the windows, dual-layer, high-density plexiglas is your best bet. It's expensive, but bulletproof glass is not the sort of thing you skimp on.
