How to Paint a Car – The Ultimate Guide to Painting Your Automobile

There are many reasons why people paint their cars. For example, the current paint on the car might be chipping, the car owner may not like the original color, or perhaps the car owner just needs a change in his or her life.

Whatever the case may be, painting cars is something that many people choose to do.

If you are thinking about painting your car, then this ultimate guide can teach you exactly how to do so.

Step 1: Prepare Your Workspace

The first thing that you want to do when you are getting ready to paint your car is to make sure that your work space is clean and organized.

If you will be working in your garage, try to get rid of as much dust and debris as possible. Dust and debris can cause blemishes, so you should always mop, sweep and vacuum before you get started.

If you plan to do your painting outside, don’t park your car under any trees – leaves, pines, and sap from trees can fall on your car and interrupt your process. Further, you should definitely check the weather to make sure that it will not be raining when you plan to do your painting.

Step 2: Get Your Supplies

You will need all of the following supplies to get the job done right.

Items you will need:

  • Face mask
  • Safety goggles/glasses
  • Air compressor
  • Paint thinners
  • Primer
  • Wet and dry sandpaper
  • Powered sander
  • Masking tape
  • Masking paper
  • Acrylic topcoat
  • Clear coat lacquer
  • Buffer
  • Spray Gun
  • Buffer

If you have a smaller or midsize car, then you will need about a gallon of primer, three gallons of topcoat, and two-to-three gallons of clear coat.For larger cars, you will need 1.5 gallons of primer, four gallons of topcoat, and three-to-four gallons of clear coat.

When you are buying the paint for your paint job, there are several things that you should be aware of. First, automotive paint is specifically designed for cars. This means you cannot just buy any type of paint to paint your car with. You need to buy automotive paint.

Another thing to be aware of is that there are two types of automotive paints: waterborne and solvent-borne.

Waterborne paint is the more environmentally friendly version and has much fewer volatile organic compounds (VOCs).

Solventborne is the more traditional option and has more VOCs. So, if you are someone who is environmentally conscious, or if you are concerned about breathing in VOCs, then you should go with the waterborne option.

Step 3: Sand Your Car

Before you start painting your vehicle, it needs to be sanded properly.

Sanding helps to get rid of a lot of the old paint, to smooth out the surface that you will be applying new paint on, and to get rid of some or possibly all of the rust if there is any.

You do not necessarily have to sand all the way down to the bare metal on every single panel. However, you do want to sand all of the panels down to the point where they are very smooth.

Make sure that when you are sanding your vehicle that you use a face mask and safety goggles. This is because you really do not want to be breathing in sanded paint particles or getting them in your eyes.

Also, make sure that you use a powered sander for this process because it is much faster than doing it all by hand.

Make sure that you sand in a circular motion. This will help you to get the smoothest and most even surface possible. If there are any rusty spots, then they will need some extra attention.

If there are any areas of your vehicle that you don’t want to paint, then you should cover them with masking paper and masking tape to remind yourself not to sand them. After you are done sanding, you should wipe down the whole vehicle with thinners and get rid of the dust.

Step 4: Prime Your Car

During this phase of the process, you apply a coat of primer onto your vehicle. Primer is a substance that helps paint bond to the surface of your car, to increase the paint’s durability, and to protect the material that you will be painting on.

You should use a spray gun to apply the primer to your vehicle. Before you apply the primer to your car, however, you should do a few test sprays on some junk metal or wood that you have lying around to get used to the motion.

You will need to mix thinners with your primer. There will be directions on the primer can for the exact proportions. Once, you have the mixture ready, then you should spray your car with the primer. Try to make it as even as possible.

It will take 2-3 coats to cover your entire car evenly. You should wait at least twenty minutes between coats so that the coat can cure. Make sure that your safety goggles and face mask are on whenever you are applying the primer.

After all the coats have been applied and have dried, then you are going to have to do a light sanding again to get out any powdery effects.

Step 5: Paint Your Car

The first coat of paint that you will need to apply is topcoat. However, before you apply topcoat, you should mix in some thinner. It should say on the back of the paint can how much thinner to add.

Once your mixture is ready, then you can load your spray gun and start applying the topcoat. Just like with the primer, you want to try to apply it as smoothly as you can. The gun should be about six inches away from the car surface while you spray it.

You are going to need to apply 3-4 coats to get the best results. Between each coat, you should wait twenty minutes to an hour for the paint to dry and cure. The paint can should say on the back how long drying times are.

If any powdery residue builds up on the surface of the vehicle, then you should sand it out before you apply the last top coat.

Always make sure that you are wearing your safety equipment when you are applying the paint.

Step 6: Lacquer Your Car

During this step, you are going to do the same procedure that you did with the primer and with the paint. However, you are going to load lacquer into the spray gun instead of primer or paint.

The purpose of lacquering your car after the paint has been applied is to make the color appear shiny and glossy. It adds class and durability.

You should aim for two coats of lacquer. Make sure that you wait the appropriate amount of time recommended on the lacquer can before you apply the next coat.

If you find any blemishes or rough spots, then you should sand them down and respray another coat of lacquer. Hopefully, by this point, however, there will not be any more blemishes or rough areas.

Step 7: Buffer Your Car

The purpose of buffering your car is to get it to look even smoother, shinier, and more polished after you are done painting and lacquering your vehicle.

Buffering your car can help it to obtain that wow factor when you are done painting, and make your car look extra gorgeous. If you want to get the absolute most out of your paint job, then don’t neglect this step.

However, when you are buffering make sure that you do not overdo it and buffer one spot too much. If you do, then it is possible that you could burn the paint off, and that is something that you definitely don’t want to do because you could have to start over if this happens.

Step 8: Inspect Your Work

After you have finished the buffering, then you should carefully go around and inspect the work that you have done to make sure that it all came out right.

Make sure that there are no rough surfaces left, that all the paint has dried evenly, and that everything otherwise looks good. If there are any issues, then you can most likely fix them.

However, the goal is to not have to do any more work at this point. Hopefully, your inspection will reveal that everything has come out perfectly.

Step 9: Clean Up Everything

Painting a car can be quite a messy job. When you are done, you are going to have to clean up all of the empty paint cans, sweep your floor, throw away packaging, put away all of your tools, etc.

However, if you are at this step, then it means that the job is very close to being finished. While you are cleaning up, it is a good idea to still wear your safety equipment. This can prevent you from breathing in paint fumes and sanded paint particles.

But, once you finish cleaning up, congratulations, the job is now over, and you have a freshly painted car.
