Just finished this one. A Fujimi kit (1/72nd) I bought some considerable time ago. When I came to build it the decals had all crinkled up and were totally unusable. After a lot of thinking, head scratching and internet surfing I finally did two things:
I bought a second kit at great expense from the usa (there seems to be a world shortage of Fujimi kits) which had decals for one and a half models. To get to double up the additional decals I neededI bought some water slide sheets (both clear and white). I scanned in the decals from the new model and I was eventually able to print some off. These incuded the Japanese roundels and the black roof patches. I was quite surprised how weel the printed decals went on - they were very thin.
The model was airbrushed with mr hobby paints and Fiat white and then varnished.
