Should the entire car be polished after a full-body paint job?

Whether a car needs polishing after a full-body paint job depends on the owner's personal usage needs. Generally, surface defects such as coarse particles, whitening, and sandpaper marks may appear after painting. To address these imperfections, owners may choose to polish the car, but skipping polishing will not affect the vehicle's drivability. Polishing can remove rust spots from the car's surface without damaging the paint, especially for cars with white paint, where using clay bars provides excellent cleaning results. When polishing, it's important to consider the grit of the sanding wax used. The grit size depends on the level of paint oxidation—coarser grits are for deeper scratches but can cause more significant paint damage and should not be used frequently. Polishing can thin the car's paint layer, potentially shortening the paint's lifespan.
