Ok let me see now.....................
I know why dont you write OX26 on one can and OM15 on the other to save any confusion
. I guess most techies can read numbers and letters.
You could even paint one tin black with white letters and numbers and the other tin white with black letters and numbers. Or even green with white numbers and letters and the other Pink with deep ocean blue numbers and letters............. You see the possibilities are endless.
