I've always wanted to build the old 1/100 Prototype Dom kit, but then a junk MG Gouf Custom arrived at my house, so I used it to cut, paste, and mix everything together, and finished it this year.
However, the decals had deteriorated, so they were unusable...💦
I had no choice but to draw the markings and such🤣
I cut it like this lol
From there,

The decals had deteriorated, so I painted them all with a brush (TT) | ふっださん's Gunpla works
