You are in the part of the build that is my least favorite, Yann (@yann). Repairing panel lines and other detail that disappeared during sanding is something that always gives me problems. I can never get the lines looking consistent. Your repairs look great. I also usually ignore lost rivets, since my previous attempts to restore them have been disasters.

Hi Folks, long time no see. First of all: thanks a lot for all those nice comment and advices. Ho yes advice, I made up my mind and decided to change the color of the wheel bay, now it's metallic grey.

Then I continued building the kit before going to paint shop: Antenna, Pitot tube, masking canopy... And I tried a new technique for the panel lines. No clue if this will work...? While rebuilding the lines I wanted to check it was deep enough, and the 1st tool I got was son's pencil. Yes it was deep enough but it's also describing the panel lines so let's check the other ones. I excepting a mess with the graphite and the paint, but let's see...

Nice approach, Yann @yann
A promising looking technique. I think the grafite should do fine with paint.
I read people doing panel lines with a marker, but that didn't work well because of the ink.
With a pencil it creates very fine lines, looking forward to it.

Ditto from me, Yann (@yann). Looks good. I would think pencil would work fine as long as you didn't put the first paint on heavy. Maybe just mist it on to start. Looking forward to the results.

The color mixture looks great, Yann @yann
You might want to do some panel shading to increase the panel line visibility.

Color looks great, @yann. Maybe you can try a thin marker for the panel lines next time and see if you can get something that will show through the paint. I had a lot of trouble getting the pre-shading to show through all of the later layers, so I switched to post-shading. I noticed you had added the foot "stirrup" at the rear of the wing. I would have knocked it off 3 or 4 times by now.

Thanks a lot my friends @johnb, @fiveten, @gblair, @j-healy. Yes indeed, the pencil pre-shading did not work, I was planning anyway to use panel lines, hope this will be enough. This week I found some time to paint the upper part in dark earth (Revell 89 RAF Mat Dark Earth).

Looks great Yann @yann
Is this enamel or acrylic?
