FWIW. When I recapped my 2205 five years ago, I tried with excellent success using what is labeled on the cap" licorice" nail lacquer(ESSIE brand,) to address some area`s of the face glass..
The included cap brush was very handy with controllable application, since woman, or some men use it to do their nails.
And being lacquer, it`s drying time is very quick, compared to enamel, and it didn`t seem to react with the existing still good glass paint when feathered over it..
Just a thought folks, from my experience.
Kind, regards, OKB
