Bummer about the glue issues.
If it helps with alternative options I have been using Krazy Glue gel and it seems to be more forgiving time wise than the Loctite I also used. I have maybe 6-7 seconds of adjustment with PLA joins and then hold it in place for another 15-20 to let it set. Not sure how fast it reacts with resin. The bond is maybe not quite as strong as the more liquid and faster setting super glues but it works well enough for display models.
More practice with your new paints?
Not that I think you need it. The paint job looks great.
Didn't IG-11 wreak a couple storm troopers and one of their speeders? (Ranks as a best scene ever!)
So... new addition to the background of the display?
