If you have a steady hand you could try paint the text. Since it's so small you can make irregular lines with some space or some small "letter-dots". Works fine for me when I paint scrolls and other things for my 28mm warhammer miniatures. Looks great with some distance, but if you look real close you can see it's not letters, but when you drive the tank your not up close so I'd say it would work fine
Good luck!
