dust

[2000]

what is it on a vehicle that dust is attacted to? the sheet metal,or paint or what? the reason I ask is I once saw a thing on subs and it said that they negitivly charge the body to help keep it from rusting as rust is attacted to the positive metals. ( I might have that reversed, but you get the picture.) so here's my point...we have a ding king and a tornadoe and a hundred other cheap add ons for vehicles..............wheres the dust repellant?

Rubbing friction also creates static electricity...one thing you can do is attach 'grounding straps' to the frame of your car and let them touch the ground. I've seen these things on the rear bumpers of several different cars, they look like rubber(ish) strips with a lightning bolt on them.

I know what your talking about.......but wouldn't that cause more dust by building up static electricity?

MPPP tends to repel dust, due to it's antistatic properties.

No, they work by letting the static buildup on (in??) your car discharge into the ground. They will also help eliminate the wonderful 'get zapped as you exit' effect.

I must disagree with Don on the fact that they will not stop this "They will also help eliminate the wonderful 'get zapped as you exit' effect." It will in fact add to it. I will try to explain the best way i can, take in mind that it has been 40 years since I played with this and I feel that 2000 has hit on something here.

Years ago kids use to hang 4 rubber/leather straps off the back of there veh's (I'm still trying to research why) but do know a side effect was when a officer of the law tried to touch the veh they were getting knocked on the kister.

The static electricity was built up by rubbing the rubber/leather on the ground now if you think about it rubber/leather are insulators so there were no return to ground paths and a static field would develop around the veh and stay there in till it found a path. one of the tool we played with in "school" was the vandegraaff-machine" you probably seen it but not know what it was It looks like a chrome water tower but smaller and usual had a wand standing up right next to it.

When I use a cleaner/wax or just plain wax I can hear the static snaps under the towel and my finishes have not been lasting as long as they did in the past.

do you notice differences from other waxes?

this was what I was taught, but was willing to write it off as a urban legend.

ok help me with science.......is dust attached to the vehicle because it is positivly charged or negitivly charged? (the vehicle, not the dust.)

Just carry a Cal-Duster with you. It only takes a minute to dust off your car. Down here in Fl we go through pollen season - every day the car is covered with it. The duster does a great job.

yea, but what if some one could come up with the idea so you wouldn't have to? if you could reverse the polarization of what attracks the dust you could save some work. (I'm just looking for my first million, so bear with me. )

Hi:

Since the chassis of the vehicle is attached to the negative side of the battery (ground); I would guess that it is negatively charged.

However paint is an insulator to some degree so I am not sure how that would affect the surface of the vehicle.

I remember back in my old audiophile days, that to remove the static from an LP (record) before cleaning and playing, we used to use an anti-stat gun to remove the static charge that had built up on the LP due to the friction of the needle contact. Maybe something like this on a grander scale would get you your first million, just remember where you heard it.

now your following where I was trying to go with this. and I do know what a lp is.........still have about a dozen milk cretes full of them. ah........the good old days

2000, this is for everyone not just directed at you

Okay here's yet another analog to confuse the masses even further:

Most vehicles, helicopter rotors, and airliners are made of metal right?

If you've ever seen a helicopter flying at night close to the ground, (when it's landing is a perfect example) sometimes you will see a luminescent 'ring' around the rotor tip path. This is caused from the rotors moving through the air, (some would say, just beating the air ito submission) at a very high speed.
Obviously this is a result of the charge built up on the rotors. (i.e. friction). Ever notice that helicopters are usually grounded with a decent sized grounding strap when moored?

Airliners are always grounded properly before anything else is done when it pulls up to the gate. It's somethig we do not see, but it EXTREMELY important.

When military helicopters pick up a cargo load externally, the first thing the ground crew will do is discharge the built up charge from the chopper. I have seen people thrown 15ft off of a humvee from not holding the static probe in place properly.

Anyway, same concept for the auto too. Especially when driving on the freeway in the right atmospheric conditions. The metal body panels on your car will build a static charge. Albeit very mild, it will attract dust, and on dry cold days, give you a nice zap if you do not touch a part of the car as you exit your vehicle.

Now someone mentioned using a strap on the car near the quarter panels. That is a good idea in theory and may provide some static discharge. But to get the full benefit of it, a ground strap should be connected to a metal rod of some kind (perhaps part of the garage itself that goes into the ground?) that goes at least 6 inches into the ground. Not that far really, but then again, we're not dealing with that much charge are we? Our military requirement was to use a grounding rod that went at least 3 feet into the ground, but then again, we were dealing with a generator that could power about 2-3 downtown Chicago city blocks.

Hope this helps and I haven't rambled on too much.

helps alot and you didn't ramble one bit. as a matter of fact each word you typed got me that much closer to my millions!

was there no way to reverse the charge of the choppers? by grounding them it only release the charge, right? now with that much of a charge it would be much more difficult to minipulate, but at the level of dust attaction, couldn't a reversed charge cancell the attaction? without necessarily being discharged?
thank you for your help.

I think you'd need something quite powerful to neutralize that kind of charge! Still a safe operation in it's current format!
