Cuirassier
The parts have been dry fitted together, the joints tidied up with swiss files where possible, and where not possible, filled with “Miliput”.
If you look at picture below, you cannot see the joint between the Cuirassier’s body and his arms. You do not have visible join lines in real life, so why should your military model have them?
Showing the area where both the left and right arms join the figure.
Fill the joint with a little too much Miliput, or similar compound. Smooth off with a wet finger or spatula and try to leave slight ‘lumps’ to mimic muscles. It gives your 54mm model a better look, and it is not as difficult as it seems.
The figure of the French Cuirassier has been allowed to dry and then undercoated ready for painting.
