Nah, they're not perfect, you just aren't seeing the photos with the mistakes in them!!
Although I painted mine, I've come to the logical conclusion that it would be easier to spray the white then add black decal strips over the top.
They look real nice, but it added about 10 hours of work to the model, and I couldn't bring myself to use the 'all-in-one' decals included with the kit. Those had the roundels, call letters, and serial number all printed over the stripes...the model would have had 75% decals and 25% paint.
