Rust is a common problem for cars, particularly in areas with high humidity or salt exposure. It can cause unsightly damage to your car's bodywork and, if left unchecked, can lead to structural damage. One way to deal with rust on your car is by sanding it down using sandpaper. However, the grit of the sandpaper you use can make a big difference in the effectiveness of the sanding process. In this article, we'll discuss what grit sandpaper you should use for rust on your car.

First, it's important to understand what grit sandpaper is. Grit refers to the size of the abrasive particles on the sandpaper. The lower the grit number, the coarser the sandpaper, and the higher the number, the finer the sandpaper. When it comes to removing rust from your car, you'll need coarse grit sandpaper to remove the rust effectively.

The most commonly recommended grits for sanding rust are 80 and 120. The 80-grit sandpaper is considered to be the most aggressive and is good for removing heavy rust and pitting. However, it can leave deep scratches that require additional sanding to remove. The 120-grit sandpaper is a bit less aggressive but still effective in removing rust. It can also be used to remove the scratches left by the 80-grit sandpaper.

It's important to note that sanding is just the first step in dealing with rust on your car. After sanding, you'll need to apply a rust converter or primer to prevent further rust from forming. Once you've applied the primer or converter, you can then apply a topcoat of paint to restore your car's appearance.

When sanding rust, it's important to wear protective gear such as gloves, eye protection, and a mask to avoid inhaling the rust particles. You should also work in a well-ventilated area to avoid breathing in any fumes from the rust converter or primer.

In conclusion, when it comes to removing rust from your car using sandpaper, the grit of the sandpaper is important. For heavy rust, start with 80-grit sandpaper, and for less severe rust, start with 120-grit sandpaper. Remember to wear protective gear and work in a well-ventilated area, and always follow up with a rust converter or primer to prevent future rust from forming.
