What are some helpful tips for using sandpaper to sand your car paint?

Some tips for using sandpaper to sand auto paint are selecting the right sandpaper grit to minimize scratches and using a sanding block for slow, even strokes. Make sure to sand in all different directions, and change directions often while sanding to prevent imperfections in the car's surface.

A low grit sandpaper removes the paint from the car quickly and is best used when stripping all of the paint from the entire car. If using a low-grit sandpaper, a higher grit sandpaper may be necessary to sand out any scratches caused by the lower grit. Using a sanding block makes it more likely that any high or low spots on the car's surface are noticed.
