On any car, truck, or SUV, you have 4 layers that the scratch can go into. The Clear coat being the first, second is the color layer, third is the primer, and fourth is the steel.

No scratch is the same, each are different and unique in their own way. Sometimes a scratch is not really a scratch. If the object that has rubbed up against your car is softer than the paint on the car, it will put a special material on the paint surface. Leaving a mark that is raised above the paint, it is not gouged in to the paint itself. If the item is harder than the paint, the paint goes onto the item that hit the car.

Most marks that are left on cars, only scratch the clear coat and the color layer. When this happens you can usually get the scratch out with some buffing and waxing and a little sanding. If it goes any down to the primer and steel level, the scratch then becomes harder to get out and usually has to be professionally done. Most people make the mistake of taking the car to the mechanic to see how bad the scratch is but an experience person in the car field will tell you this, if you take your fingernail and go over the scratch at a ninety-degree angle, it will defect wither or not the scratch is setting at the clear coat and color level or if it is grounded into your vehicle. If the mark comes from rubber, plastic or another color of paint, you can rub it off with an aerosol tar or adhesive remover product.

When you cannot get the mark to come out you can try to remove it with acetone or lacquer (a basic acetone; aka nail polish remover) and a soft rag will get the mark off. If that stupid mark is still there you are going to have start hand rubbing and polishing. To repair a scratch, wash your car or the side that needs it, down with soap and water. When start drying the vehicle off, make sure that it is good and dry or this method given will not work. This is not going to remove the scratch, but it will make less or not noticeable at all.

Use black shoe polish to fill in the scratch, or any other color you prefer. Once you have put the shoe polish into the scratch, sand down the remaining material on the paint surface of your vehicle. Do not use a rough sand paper grinder. Use a two thousand to three thousand grit wet or dry sandpaper, depending on your preference. Place the sand paper in a bowl of cold water and add three or four drops of dish soap to the water to give it more slip and increase the corrective-ness of the cutting action to get what you need.

While sanding use a sixty degree angle and move up and down the length of the scratch. Stop after 4 or 5 sweeps to wash off the sand paper. You are going to do this until the bl! ack shoe polish goes away. Once the scratch is removed, let the sanded area dry and then look over the area you sanded for any signs of the removed scratch. If no signs of the scratch are there, you may paint over it with a clear coat. If you did not sand down to the primer layers you can buff the area with a rubbing compound and soft washcloth. Once the polishing and no signs of the scratch are there, you can seal the car paint with car wax.

Harnessing the power of water has been used for centuries for many useful purposes. Initially it was used for irrigation and operating various machines, such as windmills and dock cranes. But these days it has a more important use: as a renewable source of electricity.

Electricity from hydro-power can be generated in three different ways: in hydroelectric dams, using the tides, and through the ocean’s waves and currents.

Hydroelectric Power:

This is the most common form of hydro-power, making up the majority of all renewable energy produced. Electricity is produced in hydroelectric dams where the force of falling water drives massive turbines.

The advantage of this type of power is that not only does it produce electricity, but the dam helps collect water for our use, so it’s a power and water source in one. Furthermore, the force of the water is so strong that megawatts of electricity can be produced to help power entire cities.

The disadvantage is the devastating effect dams can have on plants, animals and even humans. When dams are built they flood large tracts of land that were once occupied by various species and communities of people. Furthermore, the water-borne animals, such as fish can also be affected. An example would be salmon that are blocked from swimming upstream to spawn by the newly erected dam.

Tidal Energy:

Using the tides is the second most common form of hydro-power. Here, electricity is generated by using the low and high tides.

France and Russia have successfully used tidal power since 1966. One system is used in large bays and estuaries where water from the high tide is dammed up and diverted through turbines at low tide.

Although the tides are very predictable and consistent, the problem with this system is that the turbines only operate every 6 hours (once every tide).

Another, more modern tidal energy system works where large turbines (that look like wind turbine) are sunk in the shallows, and are spun by the shifting tidal currents.

Since this system is an underwater version of a wind turbine, the technology is up to date and refined. Also, water has a high density than air, so the turbines can spin in the lightest of currents.

The disadvantage with this tidal power system is that it can only operate in shallow area. This is usually where other economic activities, such as oyster farming, take place, and also where marine life thrives.

Power from the oceans waves:

This is the latest in hydro-power technology. Here oceans surface waves displace and compress air that is then fed through turbines, that generate power. These systems are either attached on floating platforms in the open ocean, or built along the shore where waves break.

What makes this technology so appealing is it potential to harness over two thousand megawatts of power that the ocean’s waves contain.

However, wave power systems do have environmental concerns. Their hydraulic fluids could leak out into the ocean, causing water pollution. And the fixed structures on the coastline, can damage the natural plant and animal life on the seafloor.

Closing thought:

Over the years we have come up with advanced methods of using water to produce power. Though there are a variety of benefits to using this kind of renewable energy, there are still a number of social and environmental concerns.

The advantage of writing a cover letter for job application has become a habit for most job applicants. It is true that every employer value the importance of a job resume, but the weight of including a cover letter cannot be denied when it comes to getting the position that you want to have.

These are some of the qualities that employers are looking for in a certain job applicant- resourceful.

You have to point out that the company will benefit from your skills and expertise instead of your need to get the job because you are after the pay. Employers are always interested to make the most out of their money. This is achieved by hiring someone that can be functional and very skillful.

You can do so by relaying the message that you can make your own contribution for the growth of the company. All employers would welcome an employee that can share his abilities for the success of the company.

One thing that should be present all throughout the cover letter for application content is the tone of professionalism. All employers would be impressed with an employee with this personality.
