Sometimes there can be bubbles at corners or deca can be a bit bigger than it should be, and in this case I just carefully poke it with the knife and press it with brush
I let wash to dry around 30 min and came back to clean excess with brush slightly moistened win white spirit. This way I have more control on which part will be lighter and which I keep darker
When dried I again dealt everything with matt varnish, let it dry for an hour. And as finishing step I took AK Real Colors gloss varnish and fills all screens for glass effect.
