TC, Both my Tiger and Jagdpanther were stripped and repainted. The Tiger was my first Tank and my first time painting with the airbrush. I had the benefit of a teacher and a step by step procedure. I have noticed some talk about using salt, on the deck of my Tiger I used baking soda, the finish is ruff like painted steel. But because baking soda is a really fine grain the effect is much more even.
Also the baking soda absorbs the color and does not really require much work to complete the finish. The use of pastels is another method I have done a lot with, and continue to progress using the pastels for a number of effects. If you are interested I can provide some links or if you just use the forum search function these methods have been in many post by several members.
Perhaps you could benefit from reviewing these methods, Sax
