This involves removing any old paint, wax, or contaminants that may be present on the surface. A thorough cleaning and degreasing of the car is necessary to ensure a smooth and even finish.
Removing Old Paint and Contaminants
There are several methods to remove old paint and contaminants from a car surface. One of the most common methods is to use a paint stripper, which can be applied to the surface and left to work for a specified period of time. Once the paint stripper has done its job, the old paint can be scraped off using a putty knife or sandpaper.
- Use a paint stripper specifically designed for automotive use.
- Always follow the manufacturer’s instructions for application and removal.
- Wear protective gloves and eyewear when using paint stripper.
Deburring and Sanding
Once the old paint has been removed, it’s essential to deburr the surface to remove any sharp edges or burrs. This can be done using a deburring tool or a sanding block. After deburring, the surface should be sanded using progressively finer grits of sandpaper to smooth out any imperfections.
| Grit Size | Description |
|---|---|
| 80-100 | Coarse sanding to remove old paint and contaminants. |
| 120-150 | Medium sanding to smooth out imperfections. |

Before applying the new coat of paint, it’s essential to wax and degrease the surface to ensure a smooth and even finish. This involves applying a layer of wax to the surface and then buffing it off using a clean cloth. After waxing, the surface should be degreased using a degreaser specifically designed for automotive use.
