Although the sandblasting process is applied using quality products, this application should be done professionally. Because if even a small point is missed on the metal, it will cause the metal to rust or corrode again. For this reason, even the smallest point should be sandblasted without being overlooked. This is also an extremely professional procedure. All points should be sandblasted and smoothed so that no problems should occur as a result of air contact with metal. For this, a suitable abrasive must be used.
