Does this count? 60MU at RAF Leconfield in 1967/68 plastering all the electrical and comms cabling with this brown epoxy gunk. The donks had been removed to allow access. If it does count then WIWOL YUK!!!
Wasn't a patch on my years on 230 OCU 63/65 at RAF Finningley. As a Cpl Tech Air Radio on Vulcans, now that was truly magic in comparison.
