So, after long time I got to play with the hairspray again. Preshading layers were covered with two layers of hairspray straight from the can and then the model was painted with the base coat and chipped. I worked on the hull and the turret separately, still felt that with the hull, toward the end of the process it was getting bit difficult to get the chips sufficiently small as the base coat layer was drying. In the future may deal with such larger area it in two steps.
Now is the time for some weathering.
