I tested the white glue idea and decided that using Incredible White Mask applied with a toothpick worked better. Application was about the same but the White mask was a thicker coating that came off easier. All lenses have been masked and most of the model is now primed gloss black. Ran out of paint last night so in a short holding pattern right now.
Ordered some paints today, something very different from my normal fair. Can't tell you what yet - don't want to spoil the surprise. I do have to test the idea first though to make sure it will work as expected.
