Why is sanding necessary?
Before you paint a vehicle, it is essential that you sand away the old car paint. The proper use of automotive sandpaper helps in smoothing out cracks, dings and other imperfections and is an important step when restoring a car. If you are restoring an old car or changing the paint color of your vehicle, it is necessary to sand the surface first. Which sand paper to choose? If you are planning to sand all the paint and primer away, you may choose a rough 80 grit sandpaper to finish the job quickly. Also, note that low grit sandpaper causes scratches on a vehicle's surface. To remove all traces of scratches, you may use higher grit paper, such as the ones between 800 and 1000.
- 40 or anything below 100 Grit: removes paint and heavy rust
- 100-200 Grit: prepares metal with rough surface to help body fillers to stick to it
- 200-300 Grit: helps to prep the car for primer
- 300-600 Grit: prepares primer for main basecoat paint
- 600-1000 Grit: removes large paint runs, dirt, and imperfections
