Aviation
Runway, taxiway and airframe. Two different jobs with the same constraint: the surface underneath is the asset and it does not get touched.

No media, no deformation
Alloy that has to stay the shape it is.
Abrasive blasting peens an alloy skin and changes its shape and its fatigue behaviour. Water at a pressure chosen for the coating strips paint and primer without deforming the substrate, and leaves nothing behind to find later in an inspection.
- Aircraft paint stripping, down to primer or to bare skin depending on the specification.
- Runway rubber removal on touchdown zones, restoring the friction figure without polishing the grooving.
- Marking removal and repainting preparation on taxiways and aprons.
