Hey John, You're right. I think that's the only option. I'm just worried that when I will remove the stick, either the window will come as well or the patafix will remain on the window. But let's try!

Hey Spiros @fiveten. Thanks a lot for your comment. And thanks for your advice. I will follow this method (Tks guys @fiveten, @johnb). I've been pretty busy last week (renewal of my son's bedroom) and had no time to progress on the liberator. But I will restart from today.

Looking really great, my friend @yann!
Yep, she has the best of company: great looking Flying Fortress!
Loved following your thread, looking forward to see her posted at the headlines!

Great result! - thanks for sharing.

Yann, it turned out much better. Well done. BMF are difficult in any scale, but on a large air frame like a B-24, more so. Lot of ground to cover for almost a perfect finish before airbrushing the metallic. It shows everything if you missed a spot in the sanding. Really love the results.
