I've been using the snot out of my F1 and started noticing that the yellow paint line indicators on all the knobs is wearing off, and , in fact, on two of them, completely worn off. Is there a good paint available to re do the lines, or a known replacement paint especially for them ? I was thinking about just getting replacement knobs, but they are impossible now to pull off. Any suggestions welcome. I was thinking of gold nail polish or something like that.
