Hi all, I've been working on a tamiya 1/35 M60A1 as a project to gift a friend. As such I want it to be pretty sturdy incase he bumps it etc

Well in my weathering phase the back plate separated from the top plate and its very loose, starting to bring up the top panel of the vehicle.

I need some advice on how to repair this without damaging the paint (primer, base coat, 2 coats of gloss) I was thinking careful super glue application with a tooth pick, but it would be quite visible.

Any advice is appreciated.
