The origin and Source of Electricity


Atoms are made up of electrons and a nucleus.

Question: What is an Atom and What is a Nucleus?

Answer: The nucleus is made up of neutrons, (no charge) and positively charged protons, leaving it with a net positive charge.

An atom, at the simplest level, can be thought as a mini version of the solar system, with the nucleus like the Sun, and the electrons going around the nucleus, like the planets.

The electrons move around the nucleus because they are attracted to the nucleus because positive charges attract negative charges (opposites attract).

An atom has an equal number of positively charged protons, and negatively charged electrons, leaving it neutral.
Question: What would happen if we removed some of the electrons from the atom?

Answer: This would leave the atom with a net positive charge, leading to static electricity.
You will notice this when you rub a balloon against your hair, like this boy:

Rubbing the balloon against your hair removes electrons from the atoms of your hair, where they migrate to the atoms of the balloon. This leaves the balloon negative and your hair positive, which leads to the attraction of the hair to the balloon.





The problem of waxing your car and dust attraction

The topic of dust attraction to car paint comes up often and the usual trend of the thread is to lean towards people looking for products they can apply that will reduce and even prevent dust attraction. The way this would be done is by creating a neutral electric charge to the surface of the paint. Sounds simple enough - right?

Question: How could a person create a neutral electric charge to the surface of their car's paint?

Answer: It's pretty much technologically impossible to do, (at this time), and drive the car in the real world.


First I'm not a chemist but I've been told by a chemist that the resin used to make clear coat paints in and of itself has a high static charge. That's not a charge that's on the paint, that's a static charge that's in the paint. So it's pretty hard to change the charge of your car's finish without removing the paint, which defeats the purpose of polishing and waxing your car to make it look great.


Second Even if you could create a resin with a neutral charge, the dust, dirt and air-borne contaminants in the air, that fall and land on your precious car's paint, have their own electrical or static charge and you and I cannot wave a wand and remove all the static electrical charge out of all the dust in the air in the world, or at least the part of the world that you drive and park your car.


With current technology with both surface coatings and car appearance products, there's not a lot you can do to prevent dust accumulation because the problem is with two things you cannot change,

• Your car's paint
• The dust and air-borne contaminants in the air around your car

Conclusion
Because just the act of WIPING a cloth over the surface of your car's paint creates static electricity - regardless of which type or brand of product you're using - static electricity is always going to be an issue.


The one thing you can do is use products that create a high-slip surface so that dust can be easily wiped-off or blown off then always have clean, uncontaminated microfiber towels on hand along with your favorite spray detailer and/or a great source for safe, compressed air.

A little story...
Professionally and as a curious detailer I've done numerous wax test over the years. My background has given me the opportunity to see how chemists and others would test a wax and from this experience I've followed their procedures and came up with a few of my own tests.


It all starts with a controls
Anytime you're testing, you have to have "controls" in place in order to measure or gauge against. A good control is a factor that can remain a constant throughout a single test or multiple tests.


The best test panels
A painted car hood or trunk lid usually works well as a control but generally speaking, it's important that the painted panel be factory sprayed paint as this is what the majority of your readers will be working on.



Old School Solvent Evaporation Lacquer
Sometimes I will test on straight, solvent-evaporation single stage black lacquer because it's the best test for things like a dulling-effect, scratching and sub-surface staining.

I have a test panel that's actually a table with a sheet of plywood mounted to it and hinged, and on top of the plywood is glued a sheet of sheet metal. The sheet metal surface is divided equally into two parts, on half is a basecoat/clearcoat paint system and the other half is single stage, lacquer paint.

One time there was a product about to be introduced and I was told the product had the "Green Light" to go into production. I looked at the product and the first thing I thought of was to test it on the lacquer paint. I knew everyone else was testing the product on modern, clear coats and the results were good. I tested the product on both sides of my test table and sure enough, it scratched the heck out of the lacquer paint. I took on picture, filed a report and the new product was dead in the water never to be resurrected again.

The point being that while generally speaking modern clear coats are harder than old fashioned solvent-evaporation single stage paints, there are some modern clear coat formulas where the paint is actually very soft and you can scratch it just by looking at it the wrong way and when you bring out a new product you have to have assurance that the product will work on the widest spectrum of known paints.


KISS = Keep it Simple Simon
A basic test is to completely clean and strip a painted finish down to a "Fresh Base" this can be done by compounding the finish to absolutely remove any previously applied products and then chemically stripping the freshly compounded finish to remove any residues left by the compounding process. The resulting finish will be a virgin top coat to test on.

The next thing you would do is to use some painter's tape to tape off defined square areas for which to apply the products to be tested. You can test a single product but for comparison testing you would usually want to test at least two or more products side by side.


Flat is Best
The best test panel is a black clear coated surface like a car hood or trunk lid. The reason for this is because you don't want any curves to interfere visually with your inspection, so a flat surface is important.


Paint it black -The Rolling Stones
Black basecoat/clearcoat paint is the hands-down best color and type of paint to test on because black shows everything, in other words, the human eye is able to discern defects and changes in before and after best on black paint because it's the extreme on one end of the color spectrum. White would be the worst and of course, it's the other extreme on the color spectrum.

With all the above in mind, all the testing I have done has been on black basecoat/clearcoat paint systems, using flat panels that you can look down on with controls in place to make documenting visual differences as easy as possible. Without going into details about the brands and types of products I've tested, here's what I observed.

All clearly defined test sections that either waxes or paint sealants were applied to attracted more dust than the surrounding paint that was stripped to a virgin top coat.

Not some, not a few, not most, but all waxes and paint sealants.

Part of the problem is that static electricity is created by the act of you rubbing your hand over the finish with a clean, dry microfiber polishing cloth. This wiping action creates and imparts a static charge that attracts dust.

Since common sense tells you that after applying a wax or paint sealant you need to wipe it off using some kind of toweling, it's a given that some level of static electricity is going to be created to the finish by --> you <-- and there's nothing you can do about it except for not wax your car.


Not wax your car
Not waxing your car is not a solution because a coating of wax or a paint sealant does two primary things,

• The primary purpose of a car wax or synthetic paint sealant is to act as a sacrificial barrier coating over the surface of your car’s paint.

• An application of a quality car wax or paint sealant makes the paint look good.

Not waxing your car just to avoid dust attraction is not a real world solution because most of us want to protect our car's paint so that it will last over the service life of the car and of course make the paint look good, which in effect makes the car look good, which extrapolated out to the finite degree makes us look good to some degree.


Apply or Die
So realistically speaking, you have to wash and wax your car regularly or your car's paint will deteriorate due to neglect and exposure to the environment plus wear-n-tear.



What can you you do?
Here's a two simple things you can do to help prevent dust accumulation.


1: Ground your car body
Ground your car's body to a known good earth ground. Often times older houses will have a copper stake buried into the ground and then hooked up to the house via wiring.

If this is the case you can use something as simple as Jumper Cables to hook onto the car's frame and then attach the other end of the leads to a plumbing pipe or something similar that is metal and a major component of the house/garage.


2: Water Wipe-down
Water acts as a natural static electricity neutralizer. Wiping your car's highly polished paint with water is an anathema to most of us as we would never do anything that would increase the potential to inflict swirls or scratches into the paint.

Spray Detailers to the rescue...
Spray Detailers are mostly water plus ingredients that provide lubrication, gloss, slickness, shine and in some cases, protection.


So while you and I would never wipe our car down with a water soaked wet rag, we will gently and carefully wipe our car's finish down with a quality spray detailer and this will help to remove static electricity as well as make the paint look great!


Hope this helps...
