Great auto painting involves a series of several deliberate, detail-oriented tasks.
If executed carefully and correctly, the result is an A+ paint job that looks professional and appealing. After a well-executed paint job, the paint will feel perfectly smooth and flawless to the touch, it will appear lustrous and shiny to the eye, and will last for many years thereafter.
It is important to understand at the outset, before beginning any automotive-painting project that the ultimate result is determined by how well and thoroughly each stage is completed. One stage builds upon the other, and hasty mistakes and errors cannot be concealed, no matter how many coats of paint and clear coat you apply.

There is no point in rushing through stages, because of shoddy workmanship, however minor at any stage, will doom all further efforts, and make it pointless to continue.
Most unsatisfactory do-it-yourself paint jobs can be traced to rushing through steps and not finishing each step thoroughly and completely.

So first rule of thumb:
Take your time to do it right, and if you make a mistake, stop and correct it. It's self-defeating to push forward without meticulous care given to each step. After all, the fundamental reason you undertook the project in the first place is because you wanted a terrific paint job you can be proud of and a car that doesn't embarrass you.

Painting a car requires slow, fastidious execution of the following general steps:
- Sanding and repairing surface imperfections, like scratches
- Applying body filler as needed
- Sanding and more sanding, using progressively finer grades of sandpaper
- Thoroughly cleaning the entire surface to be painted
- Masking carefully all areas of the car you want to protect from paint
- Applying primer
- Applying the paint color (usually three coats)
- Applying the clear coat (usually three coats)

To accomplish the project successfully, you will need a good paint gun, a compressor, sandpaper in a variety of grades, good auto paint and clear coat, a few hand tools, clear plastic and masking tape, and some patience.

Some people get hung up on which paint gun to choose to paint their car, and waste an enormous amount of time worrying over the features and benefits of the many models of paint guns available on the market. This is a useless exercise. Any reputable brand will do and many can be purchased for around a hundred dollars. The most important consideration is to choose a paint gun that feels "right" to you, one that is comfortable in your hand.

A word of warning on paints and solvents is in order: Make certain all of these products are compatible or the results could be ugly, if not disastrous. Also, be sure the compressor is suitable for the paint gun and delivers the paint to the car's surface correctly.

Learning how to paint cars is easy, and a way to save massive amounts of money. To get the best tips on how to do it yourself and paint your own car please read below.

Everyone has done it. You back into a pole, rear end a stray shopping cart or drop a heavy object on the trunk lid. The result is an ugly dent or a scraped finish. Turning in small damage claims to your insurance can be costly and if you have gotten an auto body repair estimate, you know that parts and labor can be expensive to pay out of pocket. There is another option though, you can fix it yourself. That's right. Armed with a plunger, a bottle of touch up paint and a few supplies, the average do-it-yourselfer can repair small dents and scratches. Here's how.

Unsightly Dents

If your accident has not broken the finish and has damaged a larger body panel, you may be able to pull the dent out. Dump a bucket of soapy water over the dent and stick your household plunger over the area. The water should help create a good seal and you may be able to pull the panel back into shape. The soap will allow you to slide the plunger down the panel to break the suction.

If your dent is in a small area near a crease in the vehicle, you can place a small block of wood at the tip of the dent and gently tap the wood with a mallet to force the misplaced metal back into its original shape. Tapping gently around the edges of the dent may help pop the metal back into shape. Use care not to break the finish, chipped paint exposes bare metal which will rust.

Scratches, Scrapes and Stone Chips

Most body shops will sell you a bottle of touch up paint. They will also ask you what you are repairing and offer to fix it for a large fee. Kindly decline, and request just a bottle of touch up paint. They will need access to you vehicle to get the manufacturer's paint code. This is most often found in the glove box or the door jam. If your vehicle has been painted a different hue than its original paint color, the auto body technician can use an educated guess to mix your paint to match the rest of the finish closely.

You will need a fine grit sand paper, a bucket of soapy water, some wax and buffing cloths in addition to your bottle of paint. Wash the scraped area well with soapy water, paying special attention to any bugs or tar in the area. Wet your fine grit sand paper and carefully sand the edges of the scrape or stone chip, making sure to keep your sand paper wet. Dry the area well and leave it sit for at least ten minutes to make sure it dries completely. Then, shake the bottle of touch up paint for at least two minutes. Brush on a light coat of paint over the damaged area. You can always apply a second coat after the first coat dries. Allow the paint to cure overnight then use a rubbing compound followed by a coat of wax to protect your finish
Paint repairs fare the best when done on a sunny day with low humidity. If this is not possible in your area, perform the repairs inside a heated building with a dehumidifier running. You can also use heat lamps or a hair dryer on its lowest setting to help cure the paint.
With a few tools and a little know how, you can save yourself some money by repairing small damages yourself.
