By changing the paint of your car, you can easily give it a new look. If you are not afraid of being dirty by paint and love Diy’s work, then you can paint the car by yourself.
If you paint your car with professionals, you need to spend a lot of money. On the other hand, painting by yourself provides fun and comfort.
For painting perfectly, you need the right things and information. Before painting the car, you need to prepare it properly. Here I try to discuss the full steps below, which might help you to complete the job.
Ways to Prep a Car for Painting
Cleaning the Workplace
At first, it is necessary to gather all the required things and select the workplace. Then we need to clean this area. If the workplace is not clean or there is any obstacle, then the job will be more difficult.
We need to hose down the area if we decide to work outside. By doing this process, it would help to settle dust. Also, we need to keep in mind that we do not paint under the tree. Because if anything drops from the tree, then the finishing will be ruined.
We need to know about mechanical knowledge for painting in the engine area because we do not fix the engine without mechanical knowledge.
For a quality painting, we need to remove everything from the car body. If the handle of the door, antenna, etc., is not part of the painting, then the better way is to remove that part from the body.
Washing is an essential part of a painting. By washing, we can remove dirt and dust from the surface.
If we paint over the dust, we get a layer of debris between the car’s surface and the layer of paint. It will not be beneficial for us.
If we paint with dust or dirt, then it will damage the surface of the car slowly. That’s why before starting to paint, we should wash the car thoroughly and let the car dry completely.
After washing the car and before applying the primer, we need to wipe the car body properly. For wiping we can use any remover or grease. But we need to keep in mind that the remover must be wax, oil, or silicon free.
The Quality of Surface
Before painting, we need to check the surface properly. If there are any scratches, dents, or rock chips, we need to repair that to smooth the surface.
If we paint over the dents, scratches, etc., it will look worse than before. For removing scratches and chips, we need to follow the feathering process so that we do not feel them after moving our hands over them.
To make the car surface smooth and flat, we need to repair the dent. To repair a dent, we can use a dent repair kit available in any auto supply store.
We can repair a dent in any household items, including hairdryers, warm water, and plungers.
Stripping is the first step of the feathering process. To complete this process, we need sandpaper. We need to apply it in circular motions. By doing this, we can remove the top and base coat.
We need to continue this process up to the bare metal surface. It isn’t easy to apply this process in every corner of the body with the sander. So, the best way is to use sandpaper with your hands.
If we use enough time in this process, then we will get the best result after painting.
Rust is a dangerous enemy for any metal element. Before painting, we need to notice any patch of rust on the car’s surface. If we paint over the rust, then it will damage the paint and surface entirely.
To remove the rust, we can apply a sander or sand with a hand on the affected area. After using the sander, we should apply the spray-on rust killer if the rust will not be removed. It takes 48 hours to remove the rust.
Wipe The Surface Again
After repairing the surface from the rust, dents, etc., we need to wipe the surface again. In this process, we can remove excess dirt and debris.
We can use a rag, paint thinner, or both to remove any dust. Also, we need to wait until the thinner will evaporate.
Prime is an essential step before applying paint on the car’s surface. After taking care of rust, and dents, there is still some imperfectness on the car’s body. That’s why primer is used to smooth the surface.
Before applying prime we need to mix prime and thinner very well. To know the proportion, we need to follow the manual. Before applying the primer, we need to wash our hands properly. If we use a sprayer, we need to maintain a minimum of 6 inches from the surface and spray from side to side.
We can apply two coats of primer. On the first coat, try to use a thin coat to make a smoother surface. After drying the first coat, we need to apply a second coat. But try to keep in mind that we must maintain the minimum time of 20 minutes to the 1-hour gap between the two coats.
After finishing the primer, the surface will be powdery. So, we need to apply sandpaper to smooth it.
After following the full steps discussed above, we can apply the paint. The painting process is the same as the primer. We need to mix the color as required and thinner it very well.
We must apply two coats and maintain a minimum time of 20 minutes to 1 hour between two coats.
The most common question: is painting over old paint of the car a good idea or not? If the car’s surface is scratchy, dented, or not smooth, the look becomes worse.
If the old paint is not scratchy, then we can apply the paint over the old paint. But before applying the paint, we need to rub the surface with sandpaper.
Safety Measures to Take When Painting a Car
When painting a car, it is important to take the following safety measures:
- Wear proper personal protective equipment (PPE) such as a respirator mask, goggles, and gloves to protect against inhaling paint fumes and chemicals.
- Ensure that the painting area is well-ventilated to reduce the buildup of paint fumes.
- Follow the manufacturer’s instructions for the paint and primer being used, and use them in a well-ventilated area.
- Keep a fire extinguisher nearby in case of accidents or fires.
- Store paint and other chemicals in a cool, dry place and away from heat sources.
- Be sure to keep all surfaces clean and free of dust and debris before painting.
- Use drop cloths or plastic sheeting to protect flooring and other surfaces that may come into contact with the paint.
- Keep children and pets away from the painting area.
- Avoid smoking or using open flames while painting.
- Read and follow the safety data sheet (SDS) for the paint and other chemicals you’re using, to ensure that you understand the hazards and how to handle them safely.
To properly prep a car for painting, it is important to thoroughly clean the surface of the car, remove any rust or old paint, and apply a primer or sealer. It is also important to make sure the surface is smooth and free of imperfections before applying the paint. Additionally, using a paint booth or a controlled environment can help ensure the best possible results.
