Although construction reports about the Pak 40 of GPM (Russian winter) and DrafModel (DAK version) have been shown in this forum, I want to show the results of the GPM (wheatered DAK version).
Due to all the small details there is a lot of edge painting nessecary to get rid of all the white lines.
For the edge paint I have been using a mixture of Burnt Sienna, Yellow Ocre and Black acryllic paint.
Instead of mixing a lot of paint and painting the whole model at once, I only mix small amounts of paint forcing myself to remix the paint often.
This gives the paint a more wheatered appearance.
After downloading a lot of pictures of the Pak 40 from the web, I got a fealing for the amount of paint damage and locations of damage due to opperating the gun. On the locations where the paint is chipped on a real gun, I mix small amounds of fine grained pigments through the paint. These grains do not dissolve completely but leave a rough surface simulating rust under the paint and chipped paint.
In the pictures this is hardly vissible, I'm still trying to find out how to make sharp pictures in the Macro mode of the camera.
One thing I don't like on the models op GPM is the fact that the tabs for glueing part together are attached to the parts (left part of last picture). I prefer to remove these tabs and glue them under the joint, as shown in the right part of the last picture.
This reduces the amount of edge painting nessecary and results in smoother cilinders.
