I tested painting today at the old attempt. After a bit of sanding the area wich was treated with primer: I painted this area and another one without primer: Tbh I don't see any difference. Looks like I can omit the part with the primer. Additional the small Revell potions of varnish are enough. Probably I will need two black of them for the main body. Another question is the colour of Mallorys skin. Let's see if the material's colour is good and a paint by clear varnish is enough. No decesition regarding the upper body yet. But more and more I tend to print a new one.
