When armed personnel carriers return from the field, they are rusty, dirty, scratched and the coating is chipped. In short, they are a mess. After blasting in a hanger-type blast machine (also commonly known as monorail or overhead rail blast machines), the tanks reappear in immaculate condition and paint-free, ready for a new paint coating, and ready to be prepared to return to the action.

Paint removal and cleaning of airforce and naval fleet can be achieved manually by closed circuit blast machines, or if sections are separated, dedicated blastrooms can be used incorporating manual or automated blasting processes.
