This tail light is not playing ball.
Worried about applying a tamiya masking tape over the smoke, I gave it a clear coat with PVA through the airbrush.
let it dry overnight, then masked the light areas and spayed black.
When removing the tape, the tape had melted the clear.
strange.
you can't tell in the picture, I'm just going to clear coat it now, its the last piece of this puzzle...
