Some very nice progress, Felix @fxrob
The picture shows they can look brand new. I'm sure she will look great.

@fiveten, @gblair, @johnb and @gwskat, as always thank you guys for your kind feedback!

I am definitely not going to do any preshading. Like Gary said, i will focus on oils and washes mostly. While doing some research for pictures today, i came across a few interesting images. And i noticed that small glass panel in the corner, which Eduard did not provide any masks for...and which are painted on now in my case. This lad his his covered, the same way i do:https://hamfisted-modeller.blogspot.com/2020/02/172-airfix-vickers-wellington-mk-ic-no.html

and the Airfix boxart has them as glass panels: https://uk.airfix.com/products/vickers-wellington-mkiac-a08019a?

Naturally i am a bit upset as i cannot undo the paintjob. What to do now?

Also not sure about the gap between the fuselage and the cockpit window. A bit frustrated right now.

I can imagine the frustration, Felix @fxrob
I'm not sure what the correct way is, having it painted or not. If you want to have it open, are you able to remove the paint with a toothpick for example.
The gap seems to be present on the original aircraft as well when looking at the first picture.

As others have said a toothpick will remove the paint easily. Don't rush and be patient.

I have used a toothpick to remove paint, Felix (@fxrob), and it does work without scratches if you are really careful. I have even soaked the tip of the toothpick in alcohol to help persuade the paint to depart. It also helps sometimes to carefully wet the offending paint with alcohol to soften the paint, then use a toothpick. The window can be polished to remove scratches, but it is difficult when it is already installed. If the scratches aren't bad, you can try simply brushing Future (or similar) on the window. Good luck. Windows can be frustrating.

That canopy is fighting you a lot, Felix @fxrob
You did a great job correcting it.
The shading on the geodetic structure looks really nice.

Excellent job so far despite the challenges, my friend @fxrob! Great that you were able to remove the paint and great (re) fixing of the canopy. Good job on accentuating the geodetic structure. Looking forward to your next steps!

Phew @fxrob she’s putting up a fight! Fascinating to see this taking shape! Thanks for starting this GB, such a great idea. This evening, I’m enjoying catching up with all the great work in show. On balance I feel you are still well on top in this arm wrestle! Looking first class! Knowing your love for, and excellent outcomes from Airfix kits, there is no doubt this will end up a beauty! Thanks again!
