Kits precut masks are imo not exact enough and so I created my own of Tamiya tape. Each “round” corner consist in fact 3 cutted edges: 45*, 22,5* and 67,5*.
Despite the grey blue mentioned in the kit for the interior I used dull red (2/3 Hu 132 and 1/3 Hu 70) corresponding to the interior of the preserved F-ANRO. Inner masks removed: sharp and clean contours = very satisfied. 🙂
