If there is one thing I hate about modeling aircraft it is masking canopies. To me it is just a chore. I can mask an entire model multiple times but something as mundane as a canopy is a pain and time consuming. That is why I really enjoy Eduard’s canopy masks.
Printed on Kabuki tape, similar to Tamiya tape, these masks are precisely cut for the Eduard Bf-109G-4 kit. They should fit the G-2/5/6 as well. The thing about these masks that is different from other masks is that the aft canopy has internal framework. Eduard gives you both the interior and exterior framework for the aft canopy. The other canopy parts are just the outside. The single page of instructions shows you which masks goes where.
