If you're restoring a classic car or trying to remove old paint or rust from your vehicle, you may need to sand the car down to the bare metal. Sanding a car to bare metal requires the right tools and technique, including using the correct grit sandpaper. In this article, we'll explore what grit sandpaper you should use to sand a car to bare metal.
The first step is to remove any loose paint or rust using a wire brush or sandblaster. Once the loose material is removed, it's time to begin sanding. Start with coarse-grit sandpaper, such as 80 grit, to remove any remaining paint, rust, or other debris. This coarse grit will quickly remove material, but be careful not to apply too much pressure, as this can cause dents or scratches in the metal.
Once the bulk of the material is removed, switch to finer grit sandpaper, such as 180 or 220 grit, to smooth out the surface and prepare it for painting. This grit will remove any remaining surface imperfections and prepare the metal for a new coat of primer and paint.

If you're looking for an even smoother finish, you can use even finer grit sandpaper, such as 320 or 400 grit, to further smooth out the surface before painting. However, keep in mind that the higher the grit, the longer it will take to sand the car down to the bare metal.
It's important to note that sanding a car down to bare metal is a time-consuming process that requires patience and attention to detail. It's also important to take safety precautions, such as wearing a dust mask and protective eyewear, as sanding can produce harmful dust and debris.
In conclusion, when sanding a car down to the bare metal, it's important to use the right grit sandpaper for each stage of the process. Starting with a coarse grit, such as 80 grit, and working up to a finer grit, such as 180 or 220 grit, will ensure a smooth and even surface for painting. Keep in mind that sanding a car to bare metal is a time-consuming process that requires patience and attention to detail, but with the right tools and technique, you can achieve a professional-looking finish.
