Steve, I am glad you like my car and thank you for your nice comment, and Lynn, thank you for concurring with Steve
, but really, it is not artistry, it is just patience

I did not use my airbrush to weather this car, I applied several washes of diluted acrylic paints. To make it easier to apply the washes, I started with spraying a thin coat of Dullcote . I mixed raw sienna and black to get a medium to dark gray color and then thinned the paint heavily with water. If you can clearly see an effect after the first wash, then the color needs to be diluted even more. It will take several washes to get the desired effect. In this pic you see, how the car looked after about 4 washes (the patches were done after the washes).
Apply the thinned paint with a soft paintbrush, don’t drown the car and avoid to create puddles, especially at the end of the strokes when you lift the paintbrush off. If the paint is dripping off when you apply the first wash, take a soft rag and rub the car dry with it (taking care not to damage any details). The next wash should work well. You can speed up the procedure by carefully drying the washes wit a hairdryer.
I did not want a rusted roof like on my blue GVSR car, but the procedure is the same, I only did it to a lesser extent. I mixed rust brown acrylic paint with yellow and wiped the paint on to the roof with a soft rag, not covering the entire roof and only leaving a light yellowish shine. Then I took a stiff 1/2" paintbrush, dipped it into the rust brow paint, wiped off most of it on a piece of paper and then stippled the roof with it, concentrating on some areas. After the paint had dried, I washed the roof two or three times with my sienna/black mix. The patches were done with an airbrush, using glossy paint for the black patches. And again, after the patches had dried, I gave the cars some washes with my sienna/black paint, followed by more washes with a much lighter (more raw sienna) colored paint. After painting the rusty patches and applying the decals, I only needed to seal the car with Dullcote.
All in all, a lot of work and patience, not much artistry
. To weather a car with an airbrush takes much less time, but it is very unlikely that you ruin a car when weathering with washes ... and if you don’t like the results, you can wipe it all off again with a moist rag, if you don’t wait too long.
