Summary
This safety flash summarises JFD’s investigation of lacquer blistering and excessive aluminium-neck corrosion in COBRA’s 2L composite cylinders. It distinguishes manufacturer assurances about lacquer defects from unresolved batch concerns, and advises external-condition checks whenever sets leave the dive system, with replacement and IDEST inspection before re-use where condition is questionable.
