Creating the legs 😙
The blue parts are sprayed with matte clear coat 😙
The gray parts like the joints are sprayed with silver on the runners, so I shaded them with a gray marker to create a dirty metallic look 😎
The parts that will be visible when the joints are moved are lightly painted with burnt iron 😎
Otherwise, if you're using a weathered finish, even a slight peek of the beautiful molded color will be quite noticeable 😜
