after a number of experiemts, I finally achieved something I dare to show here. Actually, I can't wait to show it
My first batch of Class 156 cars gets painted.
First, I sprayed the mounted cars with Tamiya primer. Three thin layers.
Second, I painted the roofs (after having covered the sides) in gray. Especially the front sections are tricky.
A closeup reveals that not everything is perfect, but, well, this is T ...
And then .... ta ta ... decals attached to the sides do the job. They do actually two jobs, coloring and window glasses! It needs some practice to place the things exactly where they belong. But I think the image shows: this technique is not the worst. It is applicable to a wide range of models. The decals are printed with my ink jet, so it is very simple to generate different coloring schemes etc.
I will show more images once I have treated all sides and put the cars on wheels.
