    Long-term outgassing leaving a film on your glass is a problem with that stuff.

    I suppose I should ask if there is a recommended technique/tools for applying the Speedball ink to the edges of the glass, e.g., is a primer of sorts necessary? Foam "brush" OK? Drying time like any other ink?

    Glass Negative Carrier Leaking Light at Edges of Glass

    Clean the edge with isopropyl or acetone — just sort of a good practice — then use a small paint brush like what Bob Ross would use for painting happy little trees. I had a chuck or vacuum pen at work that I could put the lens on and turn as I painted, but at home I hold the lens between thumb and finger — gloved of course — and turn it as I paint the edge.

    If you mess up you can clean it off with isopropyl and reapply.

    Guess it depends on the exact formula of Black Cat. Mine dries fast and outgasses fast, even in this foggy climate. There might be a tad of glycol in it to enhance flow. Dunno. But any enamel paint outgasses much much slower. The vinyl used in some enlarger bellows is a vastly bigger problem in terms of glass "windshield smudging".
