So after many failed attempts finally found her on amiami and jumped at it. Now in the aftermath she is a “C grade” for fading on the top of her head/hair.

So question-confident in my airbrushing (from gunpla). Is it unreasonable to touch up or blend in the fading spot or is it best to avoid any touch up in your experiences? Don’t plan on ever selling it but as a collector is this more trouble than it worth (paint compatibility issues etc?)
