Here is another update, I finally received my Centauri Balvarian's and I'm using the hangers to add them to my Supper Assault Carrier. What I am doing is adding superglue and baking soda on the sides of the hangers to get a smooth side. That is the beauty of those two ingredients. When combine, it hardens into like plastic. After that, it's sanding the sides and adding a layer of GW's Liquid Green.
I still have a lot of sanding to do and some small modifications to do.
