Windshield Protection

[dzzz]

Anyone give much thought about protecting the windscreen? The huge U500 front window just begs to be broken.
Here's a truck from one of Doug Hackney's interviews. I was thinking screen, but this looks like plexi.

The Turtle IV has a flip up mesh gaurd.

The Turtle IV has a flip up mesh gaurd. Those are abundant in the Outback,Australia. They called them "stoneshields". They also had Roo Bars that completely surrounded the vehicles. I hope I got the terminology right. It's been 31 years since I was down there.

I've been contemplating same -- that $$$$ U-500 heated windshield is just begging to be broken. I think when the Van Pelts spent their year in South America with their U-500 they took a hit but were fortunate to be just a few miles from a place that could repair it before it spread. They reported that it was a substantial fear much of the time. Mike said that he'd often pull to the side of the road or sometimes he'd steer towards the middle of the road to physically block / scare the oncoming bat-out-of-hell traffic into slowing down. He probably didn't want me writing that last, tho ;-)

In any case, I've been wondering what the appropriate screen size and material might be. I see border patrol vehicles running around these days with full window guards with what looks like about 1/2 inch grate -- but that's to address large stones actually being hurled at them. Plus I've had smaller rocks than that take out a windshield. Could it be that "clear bra" adhesive material might offer enough additional protection? It'd certainly be the simple and relatively cheap but I don't know how that interacts with wipers and what it's like to look out through the material vs just through it to paint.

Windshield repair kits are about $10. While maybe not as clear as the two part professional system, the repair is probably as strong. The use of a do-it-yourself kit precludes later professional repair.
Anyone have a link to a professional kit?
I'm thinking about a stainless steel screen covering the bottom ~40% of the windshield. A full screen would be very tall, and I expect I would leave it off. Bottom 40% coverage may reduce impacts 75%. I've never had a rock hit high on a truck windshield.

[charlieaarons]

I have about 6 rock dings and a crack that is horizontal a couple of inches above the bottom that angles up on the passenger side, therefore doesn't affect vision for the driver at all.
I have a spare heated windshield I plan to install after I return to Alaska. Got it for $300 + shipping from Unimog's amazing "out of business" sale (also alternator, rectifier, air compressor, special tools...)

[dzzz]

Charlie, are all your rock hits low?

[charlieaarons]

Low and middle, surprisingly mostly on right side and middle.

The common thing here in Australia is to have the lower third covered with a 10mm mesh screen - most trucks in the outback have them and I would not be driving something like a U500 without one - not unless you have a couple of spare windscreens in the back. Road trains throw up a tremendous amount of rocks when driving at 120kph down a dirt highway - and they are much bigger than even a U500 - 90 tons of truck has right of way regardless so you have to move over for them.

When you come over Charlie, talk to a truck supplier or truck service place, they should be able to get one that can be made to fit, alternatively get one made up before you ship it across.

Roo bars are what you guys call bull bars or brush bars - the main difference is the size and the angle when fitted on a truck - here they are made to push the animal under the truck - so they have a forward rake - you don't ever want an injured roo through your windscreen

On an aside - roo bars on their ute is a "must have " for your average outback jackeroo, a 5 post roo bar and a RM Williams or Caterpillar sticker, massive bull lights on the roll bar and big mudflaps right across the back are supposed to drive the outback girls wild with desire :)

I installed windshield tear off for a trip to Alaska that worked great. Its used in the racecar business and comes in several layers. Mine was a 5 layer product. It washes and cleans and when it is to scratched to bad to use you tear off a layer and its as good as new. Its mostly good for flat windows or has to be pre formed to fit your windscreen which comes at a cost. I used a piece from a stock vehicle so I didn't install it on the whole window only the lower vulnerable parts but it didn't matter. it cleaned the same as glass but I had to hand wipe after the squeege because of the edge thickness.

I installed screens over the headlights in S.A but often just slowed or stopped if traffic was to fast and as noted above sometimes tried intimidation. (Intimidation is easy in a Unimog) If your vehicle is not moving you seldom get the rock.

[dzzz]

Michael, that's an interesting approach. Will you continue to use the sheets?

You make a good point. Rocks don't usually hit windsheilds. Vehicles hit rocks thrown in the air.

[michaelvanpelt]

Its an expensive product and not easy to get but I liked it. However for S.A I just chode to go on the defensive and slow or stop. For me its what's outside the windows... slowing down to enjoy nature is best for my personel preference.

Here's an image I probably stole from Doug Hackney.

Note the front corner protection above the bumper. Nicely done.
Is there any advantage to the sun visor as compared to a tint strip at top?

[skysix]

Low and middle, surprisingly mostly on right side and middle.

If you are driving "normally" (ie: not RHD lke UK) I would expect that. More small gravel and loose rocks on the shoulder and between the most commonly used area of the road - the ruts if you will - in the tarmac) than elsewhere so more likely to get picked up and thrown...

[dzzz]

Any U500 owners interested in a "group buy" on a windshied screen? Perhaps an Aussie company already making screens, or a U.S. custom shop. I'm not aware of any Oz U500, so that may be a problem getting it from "down under".

I'm thinking the best attachment points are where the snow plow lights mount. It seems that it should be possible to attach both the screen and the lights. The one custom attachment point probably should be centered (below the windshield). Height to be discussed.

I am interested, Is this still a possibility?

[Iain_U1250]

Hi Roberto - I will be contacting our local manufacture of the stone screens for my U1250 in the near future - I'll let you know if they can make one.

[charlieaarons]

I now have an unheated windshield and even for that MB Australia
had to get it from Singapore. I changed on arrival in Sept, had a bad hit on the Alcan.
Surprisingly no dings in 16kkm Aust. driving so far. However on this most recent trip almost all dirt roads were closed due to rain. Hopefully in late June when we go back to the NT and Kimberly things will be dry.
Incidentally I'm very happy with my EGR "cure". I'm experimenting with an 800hr/28000mi oil change with Delvac 1 SHC oil.

Charlie

PS I think the cure for oncoming
road trains or speeding smaller
vehicles is to slow way down or stop.

Anyone using a security window film such as ShatterGARD (http://www.shattergard.com/home.html)? I've been thinking about this stuff, but don't know of any real-world accounts from anyone using it.

[MultiSmog]

Hi Roberto - I will be contacting our local manufacture of the stone screens for my U1250 in the near future - I'll let you know if they can make one.

Thanks Iain. I just remembered that 3M makes a similar product that is used in Mexico to prevent smash and grab in cars.
I will do some research on it.

We have a shatterguard product on windows at our shop. They will keep the glass intact against baseball bats and apparently will protect against fragmentation from grenades (haven't tested it myself). I know that alot of the banks (and even stores) use the product around here.:coffee:

[dzzz]

Not the right product. The security products hold the glass togeather after breaking. Racing-type products protect against chips.

Security film is on the inside. Chip protectors are on the outside.

[762X39]

I am not sure if it is the wrong product or not. The literature and video shows a baseball bat and hammer whacking against the glass to no effect and a grenade fragmenting (as they normally do) nearby and the glass only shattering but holding together. If it really can survive that I suspect it will prevent a windshield from cracking and may be worth a look. Of course since I am no longer enlisted I see no reason to be concerned about the grenade survivability.:coffee:

[MultiSmog]

Not the right product. The security products hold the glass togeather after breaking. Racing-type products protect against chips.

I agree with you, it depends on which side of the window you install it.
If you intall int inside it will not protect against chips but it now get scratched as easily. If you install it outside it will not hold so well against larger strikes.

I assume that both products are PET which is virtually indestructible, just try to rip apart a water bottle.

Hi

I've put some Lamin-X on exposed corners and the bonnet leading edge etc, and so far its good stuff. A 3M product, as originally used on heli rotor blades (although maybe different thicknesses).

In the UK you can buy a 12" x 5' piece for £35 +del from

http://www.lamin-x.co.uk/shop/paintprotection.htm

Many others do "pre cut to fit your Porsche" sets, and I'm sure you could get someone to laser cut a set for a Mog, but you can't really see joins unless you look carefully. Compound curves are hard to fit in one piece anyway, and practice is required!!

I did ask if I could have a longer strip (the more you think the more places you can put it to stop scuffs etc, so I've maybe had 5 pieces in all), and from the USA I got 12"x15'. This was to cover the Mogs bonnet edge in one piece plus other bits, but I screwed up and had to cut it anyway! The headlight protect stuff is I think a bit thicker.

It is entirely see thru, I saw a clip I think on utube of someone firing an airgun at it and it left no mark.

I have never found it wider than 12", and I've not heard of anyone putting it on a windscreen, but I don't see why not? It may be illegal in the UK to stick anything on the screen so I hadn't thought of it till reading this :)

Or buy an SBU and have a nice, flat, easily replaced piece of glass!


(The pic with "protection" parts just above the bumper dzzz refers to is an aero aid to improve mpg I think?) :)
