[header] How to wet sand a car [title] Determine if wet sanding is right for your car. [step] Wet sanding can be an excellent way to restore your paint to its original luster, but it isn't always the best option. Deep scratches that reach the metal, for instance, often cannot be repaired through wet sanding alone. <sep> (A) It might be a good idea to go down to the trunk of your car and ask around for a dry sanding can. Dry sanding makes working with your engine easier and less expensive. (B) If the clear coat on the paint has scuffing and scratches, however, wet sanding may be the right solution for you. [substeps] Scratches that are deep enough to expose metal cannot be resolved through wet sanding alone. (C) Giving it a try might result in significantly better results in the car having fresh paint.
