Spray painting is a low-cost method of painting an automobile. Clean and sand the car’s surface to produce a smooth substrate for the primer to adhere to. To obtain a high-quality finish, apply repeated priming and top coats. Even though spray paint is a quick and easy way to paint an automobile, it must be used with caution. Wear a mask and goggles while spray painting in a well-ventilated environment.

Preparing the Surface of the Car

1. Sand the vehicle with 600-grit sandpaper. Using 600-grit sandpaper, sand down the metal surfaces of the area you’re painting. Back and forth across the whole region with the sandpaper. The paint on the automobile will begin to flake away gradually. Switch to 1500-grit sandpaper after the bulk of the paint has been removed. Make certain that any corrosion on the automobile has been carefully polished away.
This is a time-consuming operation, but it will significantly improve the appearance of your paint work.

2. Putty may be used to fill any gaps in the metal. Rust removal may occasionally leave holes in the metal. Fill up the gaps with a putty made for vehicles or metal. Squeeze the putty straight from the tube into the hole, covering it completely. Using a flat-edged putty knife, smooth the surface and remove any excess putty.

  • Allow the putty to cure for an hour before sanding with 1200-grit sand paper.
  • Car putty is available online or at a hardware shop.

3. Using a dry towel, clean the car’s surface. Using an old dry towel, remove any dust or grime from the region. If there is any wax or tenacious dirt, use cellulose thinner to remove it. This will aid in the dissolution of wax and baked-on grime. Using an old cloth, apply the cellulose thinner to the affected region. Because it is incredibly strong, you will only need a tiny quantity.

  • A hardware shop will sell you cellulose thinner.
  • Because the fumes from cellulose thinner may be harmful, it should always be used in a well-ventilated location.

4. Using painters tape and paper, cover any parts that will not be painted. Cut painters tape into strips and use them to cover any exposed areas you don’t want to paint. Tape sheets of paper over the surface to protect it from the spray paint if you’re attempting to cover a big area, such as a window.

  • Remember to cover any non-metal parts, such as automobile bumpers, wheel rims, side mirrors, and window frames.
  • Painters tape is available at any hardware shop.
  • If you don’t want paint on the ground, put paper beneath your automobile.

Priming the Car

1. Use the spray cans in a protected and well-ventilated area. Aerosols operate best in warm, dry, protected environments. If it’s chilly and wet outdoors, work inside a well-ventilated garage. If possible, avoid dampness since it makes drying the paint more difficult.

  • Keep your vehicle away from anything you don’t want paint on.
  • To protect yourself from paint fumes and dust, put on safety goggles and a dust mask.

2. Apply three coats of primer, pausing 15 minutes between each. Apply the primer to the automobile at a distance of 25 centimetres (9.8 in). Spray primer all over the surface you’ll be painting. Push the spray button gently down and slide the can over the surface in even, back and forth strokes. To obtain an even coat, move at a constant rate. Wait 15 minutes before applying the second priming layer. You’ll need at least three coats to obtain an equal coverage. It is preferable to apply numerous light applications of primer rather than a few heavy coats, since thick coatings might cause the paint to leak.
Allow at least 24 hours for the area to dry following the last priming layer.

3. Sand the area smooth using 1200-grit wet and dry paper. Wet the sandpaper and wipe it back and forth over the priming layer until it is smooth and even. To obtain a clean finish while sanding a wide area, you may need to use many pieces of sandpaper.

4. Warm, soapy water should be used to clean the region. Using a towel and warm, soapy water, remove the dust off the automobile. Rinse the vehicle to eliminate the soap suds, then towel dry the surface (or wait for it to air dry).

Spraying the Car

1. Shake the paint container vigorously for at least 3 minutes. Because the pigments in the paint separate with time, you must aggressively shake the container to re-combine them. If you’ve shook and used the can within the past 12 hours, you simply need to shake it for 1 minute.

2. On a scrap of cardboard, test the paint. Spray the paint from around 25 centimetres (9.8 in) away from the card. Examine the card to ensure that the paint was applied evenly. If it’s spotty, shake the can for a few minutes longer.
A test spray allows you to explore with how much pressure you need to apply on the spray button.

3. Using horizontal strokes, spray the paint onto the automobile. Hold the can parallel to the car’s surface and about 25 centimetres (9.8 in) away from the vehicle. Spray the paint over the automobile in even, back and forth strokes after pressing the spray button. As you move your arm over the space, maintain the can parallel to the automobile. Continue spraying until the area is covered with a light uniform layer.

  • Attempt to move the can at a constant pace.
  • To obtain an even coat, move your arm over the area at a regular pace.

4. Apply at least two coats of paint, allowing 10 minutes between applications. Using many layers of paint will result in an even surface on the automobile. Allow 10 minutes between coats before applying the next. The paint should still be somewhat sticky; this allows the next layer to adhere to and mix with the prior coat.

  • If the surface remains spotty after two layers, add another coat after 10 minutes.
  • Allow the paint to cure for 30 minutes before adding the clear paint.

5. Using a horizontal motion, spray a coat of clear paint over the area. Push the spray button and move the can in a smooth way over the previously painted surface. This will assist to protect the paint from the sun’s UV radiation. Allow this coat to dry for 24 hours before driving.
