I'm looking for a good method to make sure the seams are clean on 1/700 models. At the moment, I airbrush a layer of paint, which looks like that with green and black paints: (Don't consider the red circle)

It is very efficient but I would like to have a "dry" method, which would be faster (No drying time) and it would also allow for pictures of the ship before painting, with all modifications visible.
Thanks in advance,
Arnaud
