*Equip your vehicle with a Smoke Screen, Armor.

Posted: June 8, 2009 in 2009, Exclusives

Have a dense smoke fog eject from your vehicles exhaust pipe, without damaging your engine. I saw this in a show called “Ultimate Bulletproof Car”. It’s quite simple and cheap by my estimation.

The concept is simple: add a 2nd sort of windshield washer fluid tank under your hood, fill it with everyday radiator ‘antifreeze’, and hook it the exhaust manifold with copper piping. In-line you’ll need either an electronic valve, or perhaps a pump, but I’m not sure; 12 volt either way. The kit this site sells only uses a valve to release, but their pricey can of smoke solution is aerosol, so a pump might be the more likely part needed in an antifreeze setup. For you big screen TV pillaging survivalists: ‘antifreeze’ primarily consists of ethylene glycol, the same nasty fluid found inside the 3 projector lenses, in high grade form, which happens to be the largest problem in waste disposal from scrapping out rear projection TV’s. BTW: projector lens coolant costs about 10 times as much as vehicle radiator fluid.

To hook into the exhaust manifold I recommend using a brass flare fitting, and you’ll need a matching “Tap and Die” bit to create the threads. I haven’t yet done any this, so it’s possible the manifold walls are too thin to tap proper threads into. In this case a ‘bulkhead’ method might be required which could suck, requiring removal of the manifold. I’m also unsure of whether or not a sprayer nozzle is required inside the manifold chamber, but if so a salvaged fuel injector sprayer would likely be ideal.

Without major complication, I can see this project being completed in a Sunday afternoon for less than a hundred dollars. I also see where people experienced in this practice could make some decent side cash by outfitting others vehicles after showing off with this ‘James Bond’ tech. I imagine there might be several sites containing more detailed info on the process, but the one I linked above is the best one I found in about 5 minutes of searching.


Vehicle Armor: I’ve seen some episodes from the new show “Weaponizers”. In one episode they do armor tests using plate steel. I can’t remember if it was 1/4″ or 1/2″ plating, but the results weren’t too impressive using 30 cal. rounds, especially not for the weight added to the vehicle. But this reminded me of a show I watched many years ago on ‘Armored Cars’, the type used for cash transportation between banks and so on.They don’t use steel. Instead they use several layers of thin aluminum, and achieve better results using less weight. The bullet resistance is dramatically higher than if they were t use a solid thick aluminum layer of the same thickness.

A key form of bulletproof glass also uses layering (of actual glass), but higher grade bulletproof glass is one thick layer of polycarbonate. So with these lessons I figure that stacking thin layers of steel, aluminum and polycarbonate might get the best weight vs. bullet resistance, especially if tough adhesives (2 part adhesives and paints are always the best) are used to stack the layers together. Without proper adhesives, the metals might work better by using all idenitcal materials, and ‘weld-riveting’  them together, as welds are typically stronger than than the materials themselves. The main point is the more layers the better, which gives true samurai swords their ‘edge’ over other swords of the same thickness.

    Parents must teach their children on the proper management of waste. They should tell them that when they manage their trashes well, they would help in the preservation of the Mother Earth.

    smoke screen comment..the concept is cool, BUT! if your vehicle has catalytic converters..DO NOT DO THIS !! unless you add your system after the CAT’s, otherwise you will damage the one or two depending on vehicle.
