Your vehicle’s fresh coat of paint is only as good as the paint layer beneath it. Whether you want to prevent further rust damages, cover an unsightly blemish, or completely repaint your car, the first step is to remove the old paint. It may appear to be a difficult process, but much like painting your own car, removing old paint and rust is quite simple with the right tools and work space.

Initial Steps – Tools and Workspace

As with any vehicle paint project, make sure you’re working in a well-ventilated, clean, and dust-free environment. A covered space is preferable, but if the weather forecast is favorable for the next few days, a spot outside away from trees will suffice. Assemble your tools and safety implements ahead of time — you should always have at least a dust mask, gloves, and a respirator on hand when chemically stripping paint.

If you’re reapplying the same paint color over a blemish, first determine the type of paint and then have your paint color matched at a car paint shop. Remember that a topcoat will be required for finishing and sealing. If you’re going to paint the entire vehicle, figure out how much paint and topcoat you’ll need and put it all together.

Before beginning any paint removal, always thoroughly wash your car and allow it to dry completely.

Remove Car Paint – Sanding

Sanding away the old paint is an excellent method for removing paint from vehicles that do not have multiple paint layers. This method is also useful for removing rust or small blemishes because it does not necessitate a large amount of equipment or paint to complete the job. When removing rust spots, keep in mind that after sanding away the rust, you’ll need to treat the area to keep it from spreading.

Sanding Process

Before you begin, make sure you have a dust mask and gloves on and that you are working in a well-ventilated area. Using 220-grit sandpaper, sand where you wish to repaint until all the paint has been removed. Wipe the surface clean, then sand with 400-grit sandpaper until the area is completely smooth. Wipe the surface clean again to ensure no residue is left behind, and wash and allow your vehicle to dry before continuing with any painting or sealing.

  • Tip: While sanding by hand is effective, a dual-action sander will be saving-time. There are a variety of sanders available that will also do the job, but dual-action sanders are the most popular. Keep the DA sander flat against the surface at all times to avoid dents or gouging. Heavy-duty grinders should not be used because they are powerful enough to strip away the sheet metal and further damage the vehicle.

Stripping Car Paint

Using a chemical stripper to remove vehicle paint might seem a little more time consuming initially, but works well when you need to repaint a larger surface area. The amount of chemical stripper you’ll need will vary on the surface of the vehicle needing repainting, so make sure you’ve bought enough.

Begin with a clean and completely dry vehicle, as with the sanding method. Remove any fixtures or rubber trim that surrounds the area that needs to be repainted so that the chemical stripper does not harm them. Tape or cover any windows that need it, and gather your materials: a chemical stripper (available online or at auto shops), a foam brush or rag, and a putty knife are all required. Always wear a ventilator and heavy-duty gloves when stripping car paint, and dress warmly — long sleeves and pants with heavy boots are ideal.

Chemical Stripping Process:

Pour or brush the chemical stripper on the surface needing to be repainted, and let it sit for a while recommended by the package instructions. Once the amount of time has elapsed, test a small area with a putty knife. If the paint still does not come off easily, let it sit a bit longer or brush with more strippers. Once ready, scrape the entire area clean of paint with the putty knife. If needed, apply a second coat and scrape again. Once the paint has been removed, rinse the area with water and let it dry.

Using a coarse-grit sandpaper, remove any residual paint, and then switch to fine-grit sandpaper until the surface is completely smooth. Wipe or rinse the area clean and let dry completely before moving forward with any painting.

Tip: When using a chemical agent to remove paint from a vehicle, NEVER do so in an enclosed space, even while wearing a respirator. Make sure you are outdoors or in a space with lots of airflow.

Sand-Blasting Paint From Your Car

This is another effective method for removing car paint, but it necessitates a few more tools and a larger workspace. This method is the best for vehicles that require a large area, or even the entire body, to be repainted. A compressor and a suitable blasting nozzle are required. The type of nozzle you’ll need will depend on the horsepower of the compressor, so make sure to research which size you’ll need.

There are several types and sizes of sand-blasting media to choose from. Plastic or sand are the most common media types, and a good size range is anything from size 40 to size 12.

Once you’re ready to begin, assemble your compressor and other blasting supplies. You’ll need to wear a heavy shirt with long sleeves, a sand-blasting hood, a respirator, and heavy gloves, and always make sure you’re working in an open or well-ventilated area. If you choose a plastic blasting media, cover ALL of the exposed glass, chrome, and trim on your vehicle to avoid damage. If you choose a medium one, remove all glass, trim, and chrome. If you’d like, you can cover any sensitive areas with a thick material, but test it first to ensure you won’t blast right through it and damage your car.

Blasting Process

Fill the compressor with your blasting medium and adjust the pressure to the type and size of the blasting medium. Blast the vehicle in smooth, steady motions to remove paint, and repeat until all paint has been removed.

Tip: To avoid damaging the metal, don’t linger too long over a specific area when blasting. Blasting in a specific area with a harsh medium for an extended period can warp the metal.

In short, you can now proceed with any further improvements after you’ve removed all of the paint from the entire vehicle or a specific area. Be careful and follow step by step to protect your car against damage.
