The surface treatment is mostly finished.
All that's left is washing and painting... but I feel like there might still be some unevenness in the extended areas, and the plastic sheet crumbled off while I was sanding, so I'm worried it might come off during washing too...
I was also using this as practice for sharpening plastic sheets, but maybe I should have used brass wire from the start?

The GQ Hambrabi is pretty much finished with the polishing. | マシーナリーとも子's Gunpla works
