I see my friend. However the modern paints cover much bettter than the old ones. Of course applying with a brush still can cause a trouble with that. But the airbrushing is a different thing. Most of modellers gets in trouble because of being in rush and not preparing a model to coating properly. Also it is forgotten that many paints are dedicated for airbrushing what means these colours are pre-thinned. And this results in getting a very thin layer of the paint applied. Additionally, the peeling off of the acrylic paints forces a modeller to use a primer. Usually it is a light grey primer but why it can't be of the white or another tone.
The T-28 is yellow overall, so why don't use the yellow primer ,for instance the oil Humbrol 154. In the way you can get not only the nice primered surface but also the yellow background for applying of a thin coat of the acrylic yellow paint.
