How to Paint a Car: A Comprehensive Guide to Give your Car a New Paint

Car painting and wall-painting are far different from the same thing. You will only need a few paint rollers and a can of paint to paint your house. Whereas, painting a car involves a litany of products, primers, and sprayers. The process is usually complicated, and some skills might be necessary, but it doesn’t mean you can’t paint your car.

Car painting will require you to purchase car paint guns to assist you in applying a more uniform coating of paint. Other painting systems available on the market will allow you to use an airless sprayer to paint your car.

If you consider using one, ensure you purchase from the recognized airless paint sprayers.

Preparation for the Car Painting

Whether it’s a whole new paint job or you are just touching a few scratches, there are significant steps you should follow to begin your paintwork. First, build up the damaged spots in your car with a body filler putty and sand them smooth. Scuff the entire painting surface with sandpaper to scrape the old paint and prepare it to accept fresh paint.

Clean the Work Area

After getting all the required materials for painting the car, you need to work on preparing the work area. If you are painting the car in your shed or garage, you should sweep the floors to ensure that you have enough space for your work. You can also take your job outside rather than doing it in an enclosed place.

Avoid doing your painting work under the tree as there is a risk of something dropping down from the tree.


Removing everything from the car’s body is a crucial step towards ensuring a high-quality paint job. Remove any item on the vehicle, such as door handles, antennas, and any other thing that is not part of the paint plan.

Repairing the Damaged Spots

Pull out the dents: If your car is heavy dented, you should remove the dents to smoothen out your painting surface using a dent repair kit. To remove the dents, glue an appropriate sized suction cup using hot glue. Wait for about two minutes for the flue to harden. Firmly pull on the retractable table until the surface returns to its original shape.

Filling in the dings, depressions, and gouges with filler putty: Mix your body filler material to a cream consistent in a piece of scrap board. Spread it over any irregular surfaces on the car body using a buffing pad or a clean spreader, filling the area to enable level painting surface.

Wait for the filler material to harden. It will take roughly 10 to 30 minutes, depending on the product you have used and the amount applied. You should avoid handling the putty because you might accidentally smudge the area repaired.

Sand the edges around the filler to smoothen it: Once your filler has hardened, get a piece of the sandpaper sheet. Stand in all different directions, using lateral, vertical, and circular strokes to produce a smooth finish. It is important to feather the edges of the hardened filler to minimize the chances of the ridges showing up on the finished surface.

Stripe the existing finish: Scrub the surface to prepare it for minor touch-ups. You should use a fine sanding block to get your surface ready for the car paint. You should glide your sanding block over a specific section you want to furnish to scuff up the outer surface. This will give the car surface enough texture to accept a fresh coat of paint. Ensure that the sanding block is big enough to be able to rough the existing paint efficiently.

On the more substantial parts, use an electric orbital sander to successfully remove the old paint: if the paint surface is large, fit an orbital sander with a piece of sandpaper. A high-speed orbital sander will enable you to work quickly and efficiently. It is recommended to purchase your orbital sander because it is hard to sand down to the metal base by hand.

Remember that sanding could be dusty. You should get yourself a pair of goggles and respiratory to avoid breathing metal particles, which can be harmful.

Run your orbital sander in a circular motion on the surface area you will be painting. You should apply more pressure on the sander to remove an equal amount of paint from each part of the car’s exterior surface. If you paint a different color in your car, you will need to sand all the existing paint to prevent the old paint from showing through.

Sand continuously until no visible seams or gloss is remaining: Sand a given area over and over again, then turn off your sander and look at it. If you notice edge paint lines or shiny patches, you haven’t scrubbed off the old paint. Fire up your orbital sander and rub that area again to ensure that there are no traces of old paint are left behind.

Wipe the furnished area to remove debris: Get a wet cloth and wipe out your car’s exterior parts to wipe away any dust debris generated by sanding. You could end up with debris trapped in the new paint if you proceed without drying your car.

Prime the body of your car for a new paint

Cover all the parts of your car you don’t want to get prime: Mask areas surrounding your painting area with plastic sheeting, newspaper, and use strips of masking tape to secure the edges. This will help you avoid dealing with messes from over spraying and drift.

It’s a good idea to park your car on a piece of cloth or move it outside to prevent it from messing your work area. If the part you are painting is small, you may consider removing it to prime and paint it by itself.

Use a paint sprayer to apply a base coat of automotive coat: Use a sprayer to speed up the application area process and distribute the prime quickly and perfectly. When spraying, move the nozzle of the sprayer back and forth slowly over the surface area you are painting. Ensure that your prime is thinned well-mixed and adequately before you start spraying.

Wait for the prime coat to dry: it is recommended the topcoat to have enough time to set completely before applying follow-up coats. Most primers usually take 20-60 minutes to dry and will be ready to sand in approximately one hour.

Sanding automotive primers before they get dry will cause it to rub off hence undoing all your hard work. The exact duration of the time taken for the timers to dry will depend on the product applied and how heavily you apply each coat.

Furnish the base coat to smoothen it: If you see any visible inconsistencies or uneven spots after a firm primer coat, a block sander is perfect for this kind of job. Use the sander in circular motions and curves to make it even to match with its surrounding. You should not put much pressure while in motion.

Repeat prime and sanding to ensure a quality finish: Repeat the whole procedure for at least two times for favorable outcomes. Remember that you should not sand until the prime has completely dried off. Sand the next layer after an hour. Three coats are enough for your vehicle

The Actual Car Painting

A car that has been painted well is more resistant to corrosion and lasts longer. Besides, they look more beautiful and pleasant hence keeping its resale value. Actually, the quality of the quality paint interprets the sign of the car’s overall quality for a potential buyer. Second-hand car merchants prioritize their renovation efforts on the outside part of the car. They are aware that a poorly presented car is unsaleable.

Before beginning to paint your car, you need to have an idea of the outcomes. New paint or professional repaint can only be undertaken with the necessary materials, tools, and enough training. It is ultimately an illusion to believe that you can use your household products to achieve the same results. A car paint job requires professional spray painting, and it is recommended to be done in a specific location.

Ways of painting your car

Using rollers to paint your car

Painting a car with a roller allows you to have a wide range of color choices. For vans and pickups, white radiator paint will work perfectly, and it is cheap also.

When painting using a roller, you don’t need a respiratory gas mask like when spraying with spray painting gun. You need to put a newspaper all around your vehicle to avoid messing with the floor. Always begin with the roof surface and end with the bottom part. Apply the paint to the sanctuary to ensure complete coverage.

The results usually depend on your painting skills. If you can apply the paint evenly, the results will look good and admirable.

Painting using spray paint cans

If you really want to get favorable results, then you should consider using a car spray equipment. The most crucial thing is to work keenly on each part of your car. It is advisable always to cover the rest thoroughly. Make sure you keep a distance of about thirty centimeters.

For a complete and efficient work, you should get a compressor, spray painting gun and a mixing container. Ensure you mix the paint to become thinner. Don’t forget to wear a protective mask and a full bodysuit.

You should be mindful of your arm movements because you need spray in a smooth and sweeping manner. Regulate the pressure you apply on the spray gun trigger. It is important first to practice spraying using the spraying gun before you make any attempt of actual car paint.

Painting a whole car can take around 15 minutes per panel. You will need to apply at least four coats of paint in your car. Observe a one-hour curing period before applying another coat. On the fourth coat, you should smooth the surface with sandpaper again. Wipe the surface with a clean piece of cloth. Once done, apply another layer of the paint and let it harden for about one hour.

After spraying the last coat, you can begin applying a clear coat lacquer. Follow the same guidelines and techniques discussed above. Remove the masking tape from the different parts of the car before the clear coat dries up. Do this with a lot of care since you don’t want any bit of newspaper to mess with the still-wet lacquer. Allow the clear coat to dry following the advised period by the producer.

Finish your work

It is recommended to finish your car paint job by buffing the space. This brings out a natural shine to your car and makes it appear brand new. Use circular motions when polishing the care. Do not overwork on any particular panted section, because buffing one area a lot longer can burn the fresh paint.

Car spraying Techniques that give you a proper coating

Spray painting techniques can be the difference between the great looking job when painting your car. Whether you will paint using a car airbrush, or standard spray gun, there are things you should do to help you ensure that you do the spray work perfectly and avoid wasting time and money on repeating the job. These techniques include:

Use masking tape to avoid over spraying: unless you are experienced in paint job niche, you should remove the parts of the car you need to paint. This only applies if you are only painting a quarter panel, door, or a bumper. However, if you don’t remove the parts, make sure that you tape off, using masking tape, to avoid over spraying other areas you don’t need to spray.

Car preparation is essential: Spend a lot of time preparing the car’s surface before you hook up your spray gun. Use low grit sandpaper to smoothen the surface and scrub off the scratches or the imperfections on your car surface. Remember that the more time you spend smoothening the surface of your car, the easier the spray process will be.

Spray a few light coats instead of one heavy spray: most of the first-time car painters tend to paint the car too quickly. They may be tempted to spray one heavy coat onto their cars. This will result in a paint build up. Therefore, always ensure you hold your spray nozzle for about 30 centimeters away from the car and spray with slow and even strokes. Usually, spray your strokes from right to left and not up and down.

Correct your mistakes before moving on to another coat: If you make any mistake while spraying your car, continue spraying coat. Do not apply another paint coat unless you have repaired the error. Again you should use a piece of sandpaper to scrub away the build-ups. Just ensure that you allow the paint to dry before correcting the mistake.

Take your time and don’t rush between the coats: After you have done with a coat of paint onto your car, you need to give the coats enough time to properly set before you spray the next coat. For most car paints, it is recommended to wait for about 15 to 20 minutes before applying the next coat. You should also wet sand the car with a grit of sandpaper between the primer and paint applications. This will enable you to paint your car much more comfortable and use less paint.

Taking care of Your car paint

Clean it regularly: Regular cleaning of your car is perhaps one of the best ways to protect your car paint job. Apply a high-quality automotive soap with a foam sponge. Wipe the car using straight lines, not in circular motions, and rinse it with clean water. It is also essential to properly dry your car.

Allowing the car to dry by itself leaves behind minerals from water, which is harmful to your new paint. Dry your car surface with a microfiber towel. Paper towels, rags, or bathroom towels can leave behind scratches that can cause the color to erode over time.

Waxing: Wax offers a protective seal on top of your new paint that guards it against dust, dirt, and other harmful substances. Also, wax covers small scratches and other blemishes.

Protect it from direct sunlight: Ultraviolet rays can be dangerous for your paint job. Sunlight can oxidize and fade the new paint on your car, making it appear older than it is. You should always put your car under a shade so that it will add years of your car paint job.

Use synthetic coating: Paint synthetic or sealant  coating is an alternative to wax that permeates and bonds the pores of your paint to foam a secure protective seal. The synthetic lining is easy to apply and lasts longer than a wax coating.

There are numerous steps you should follow for a successful paint job. It is a time-consuming job that requires commitment, hard work, and patience. If you deliberately miss any step of the procedure for the sake of finishing the job quickly, the outcomes may be unfavorable, and hence you may be required to do the task again.

Therefore, it is a wise decision to read and understand the steps and guidelines carefully. Car painting is not at all a stressful job. It is quite fun if you don’t pressure yourself with what you require a clean workplace and tools necessary for your paint job.
