When it comes to automotive paint, sanding is an essential part of the process. Sanding the surface before painting ensures that the paint adheres properly and provides a smooth, even finish. However, selecting the correct grit of sandpaper can be confusing. Here is a guide on what grit sandpaper is for automotive paint.
The grit of sandpaper you should use on automotive paint depends on the specific job you are working on. If you are sanding the surface to remove imperfections, a coarse grit such as 80 or 120 may be necessary. However, if you are sanding to prepare for a new coat of paint, a finer grit such as 320 or 400 is recommended.
Before you start sanding, it's essential to prepare the surface properly. Clean the surface thoroughly to remove any dirt or debris, and make sure the surface is dry before you start sanding. Also, wear protective gear such as gloves and a mask to prevent inhalation of dust particles.
When sanding automotive paint, it's important to use a sanding block or orbital sander to ensure a consistent surface. Sand in a circular motion to avoid leaving any scratches or uneven areas. As you sand, regularly wipe the surface with a damp cloth to check your progress and ensure you are sanding evenly.
When you have finished sanding, wipe the surface with a clean, dry cloth to remove any dust or debris. If you plan to apply a new coat of paint, make sure the surface is completely dry before you start painting.
In summary, the grit of sandpaper for automotive paint depends on the specific job you are working on. For removing imperfections, a coarse grit such as 80 or 120 may be necessary, while for preparing for a new coat of paint, a finer grit such as 320 or 400 is recommended. Remember to properly prepare the surface and use a sanding block or orbital sander for consistency.
