Armed with fresh Squadron White and Tamiya surface primer, I went at the shoulder seams again. Disassembled, cleaned up, and re-asssembled, this time with cement between the offending seams. Filled, sanded, primered, sanded. Looking better.
And with a fresh coat of black. Now I'm out of Tamiya black. All in all, I didn't used to consider the Tamiya paints much, but boy do they airbrush nice. I think I'll call the seam filling done, and move on to my pre-highlighting. The seam fill itself is iffy as heck. if I handle the shoulders much more, it'll probably re-open. This will be *FUN* when I get to the dry transfers.
