This is Nobu, who's recently been completely engrossed in the production notes for the app version rather than the web version.
I apologize for neglecting my rounds.
When attaching the external armor, the unavoidable tasks with the clamshell kit are seam removal, surface treatment, and masking.
Recently, my presbyopia has worsened, making it difficult to see with clear super glue, so I switched to black super glue.
I haven't heard many good things about it, but it's made things easier for me with my aging eyes.
