We do. We see it any time somebody has a composite or fiber wrapped tank. That's the method on those.I have no idea what the requirements are in the UK. In the US, an epoxy embedded label is an option for a permanent mark. If this were a better option than the stamping method most often used, then I'm sure we'd see it.
That's all you really see for SCBA tanks.
