Sandblasting is one of the best techniques for removing old paint and rust when preparing a car for a new paint job. It is effective and leaves the surface smooth and ready for renovation. However, auto shops can choose from different sandblasting methods, with most service providers opting for the dustless technique. Dustless sandblasting eliminates the need for sophisticated safety gear since small amounts of dust produced. Nonetheless, dustless sandblasting has many other benefits as a surface preparation technique.
While the engine is central to your car's operation, it's the vehicle's bodywork that people see while you're on the road. The paint finish on your car is designed to serve two purposes.

Secondly, it also serves a decorative purpose, giving your car that attractive look that made you purchase it.
