I know, your is the 82", my one is also 82". The 82" verision has 631- 113 as a tail number.
When I add my Zero it into the "CMP 120 Zero ARF Build thread", I didn“t know about this thread.
So you want add only some outwearing without any rework? I did this thing with my ESM Stuka, and many people like Stuka than my Zero

I think that the outwearing on my Zero is not very successful job. It was my first experience with the plane and silver or aluminium color. [

Which paint did you use?
