Spray painting a car is a popular DIY project that many car owners undertake to give their vehicle a fresh new look. However, one common question that arises is whether it’s possible to spray paint a car without sanding.

When you don’t sand the surface, the paint may not stick properly, leading to a rough, uneven finish. Sanding also helps to remove any dirt, grime, or old paint that may be present on the surface, ensuring a clean and even base for the new paint.
The Benefits of Sanding
