Assessment Method 1) Stick the adhesive tape to the surface of the sample coating, apply uniform force for tight attachment to the surface of the sample and avoid creating air bubbles. Then pull up the tape.
    2) The tape is attached to the surface of the sample coating, and it is applied to the surface of the sample with uniform force to avoid the bubbling. Then pull up the tape from the opposite direction of 1).
    3) Repeat the steps of 1) and 2) until the damaged coating completely comes off.
    4) At this pint, you can accurately count the damage points for assessment.
    5) Cover the transparent grille on the sample, count the number of coating damage points (except the impact marks) in 101.6mm x 101.6 mm area and confirm the size of the damage pints. Technical Parameters Items VDA SAE
