Nice job, my friend @lis! Looking forward to the decals!

@gblair @johnb @fiveten

What paint to Roundel blue would you suggest to sorrect small places on national markings? This Tamiya Kit had very protruding elements of the wings, and decals in the corner of wings and this element ufortunetly very light tore in this place. I have idea to correct very fine brush and some Paint. I found it could be BS 110 Roundel Blue From British Standard. Mabye some of you had this problem in the past?

Difficult to point to an exact color number, Lis @lis
Like said by Spiros @fiveten, try to look for a color or mix that matches best based on eye judgement.

I never have much luck matching by eye, @lis. The first thing I try is to cut a small piece out of an extra decal to fill in, if you have an extra decal from the same set. Two colors that I have heard might match are Mr Color Insignia Blue (326) or Mr Paint Insignia Blue (300). These brands are difficult to get where I live, so I haven't tried either one. Good luck.

@fiveten @johnb In today's episode of the soap opera titled: "How to avoid bad karma when applying decals", it turned out that the mark on the vertical stabilizer was overlapped crookedly and stuck to the surface of the model so quickly that there was nothing to be improved (even by spilling Micro Sol on the table and floor in nerves) . Removing the decal was also practically impossible and led to scratching the surface of the painting, which led me to an attack of fury). After drinking the Gin with Tonic (without the gin) 😉 I took out a spare set of decals and just put on the place for an old new one ... and all the paint chips were tampered with after carefully masking the applied decals (I need to use two colors Flat Aluminium and Super Silver, because vertical arleone was painted in aluminium dope). And I think, surprisingly ... It turned out. The sunrise photo shows the effect of yesterday's night work and today's morning work. I might add that the Modelmaker decals stuck to me really well, except for the latter. And the brand is generally recommendable.
Special thanks to @gblair for suggesting a solution to the decals problem. The element in the wing that covers the aileron deflection mechanism is probably more protruding than in the KP model, because the decals really had a nice mountain to overcome to stick well. The minimal patch from the spare Roundel Blue decal seems to have done the job comprehensively. Attention here, for everyone who will want to make the Mustang MK.IVa. Probably this element is so protruding that no matter what decal company we use. You have to be prepared to solve the problem with a patch or a little paint. PS I bought a paint from Hataka in Roundel Blue BS 110 color. It will be useful for the future!

PS2. I see that I forgot about polish markings under exhauts! I will apllay them soon 🙂

@fiveten when you look at it very closely, you can see in the place of the decal folded, such slight unevenness from the remains of the old partially removed decal (try to look on photo) ... But I hope you will look at it with a kind eye ...

@gblair @johnb @fiveten I added Polish chessboards. This mark, characteristic of all squadrons of the Polish Armed Forces in the West, was specified in detail in the agreement between the Polish government and the British government, which agreed to its use (its form and dimensions). sometimes there were chessboards with the annotation "Poland".

The Polish insignia look nice, my friend @lis!
