Refinish application defects

Marking edges (mapping)

On the surface, visible transitions between layers of materials on the repair part

Marking edges (mapping)


  • Incorrect ratio of hardeners and thinners in materials
  • Layers of materials too thick
  • Material not hardened enough
  • The zone of transition of old materials sanded too little


  • Do the thinner test
  • Insulate the repaired surface with a primer e.g. epoxy in thin layers
  • Remove old, damaged layers up to bare steel


  • Sand, insulate and then varnish again
