Independent tests have been carried out by the TNO Laboratory in Holland and the Beschußamt in Germany. The concept of TSS ProtecTank is to enhance the existing OEM tank to be able to survive ballistic and explosive attacks. The self-sealing materials are specifically developed and are capable of sealing the entrance and exit holes caused by multiple shots and/or heavy fragmentation impacts. It's possible to convert your existing fuel tank into a TSS Self-Sealing & Flame Retardant fuel tank.
