I'm having a go at this. I plan to brush paint the colour (
Model Air).When you use it, do you brush or
airbrush the paint on?
When using paint, do you follow the decal paper instructions to coat it with two coats of Microscal Liquid Decal Film? (They advise this to prevent smudging since the manufacturer assumes that the decal film will be printed on a printer using water-based inks).
I assume that you use Micro Set and Micro Sol as in conventional decal application. Yes?
Have you tried printing (on a printer) a patch of colour and then cutting into strips? This would closely follow the method envisaged by the makers of decal film and might make the colour coat stick on more securely.
I will of course experiment but it is useful to be able to avoid red herrings known not to work or not to have an advantage.
