Hi Uwek,
Thank you for your attention, I had also noticed it myself when taking the photo, and it has also been corrected, typical case of not degreasing enough and the parts shifting
I am now in phase 2 of 4 with airbrusch work for the tower, and is now more visible
The glue:
I use Zap Z poxy 5 minutes
This is a two component glue with good results, the parts can still be corrected in time, and the adhesion is very strong.
First sand both parts lightly, I do this with grit 1000
Degrease both parts with 95% alcohol.
Little glue is then needed for a strong bond
Any glue residues can be easily removed after drying with 95% alcohol with a cotton swab or a toothpick.
I hope that the last translation is good, pictures say more than words ..
