Product Description: 

Cleaner Liquid 9PR5 – 400ml, for Aluminum Crack Detection / Car Body Repair.


  • Used to detect damage to the internal microstructure of the metal.
  • Very often large areas have to be checked for cracking to check whether other body parts are affected by a crash.
  • The testing equipment can be used either directly on welding surfaces or any surface for crack detection.
  • The control fluid (9VF2) makes these damages visible.

Note: The liquids and agents do not damage welds or the surfaces where they are used and can be easily removed from the surfaces with test equipment cleaner.
