And you are completely right!
Customised = painting. It doesn't say they scratch built or modified it or anything.
Seeing this kit that is made by a third party and not bandai is like a middle finger to bandai.
I was thinking the same thing. I have that very kit (have not put it together yet), and the finish looks pretty much the same, just some black and red in certain areas. Still looks good though
