Thanks for the feedback guys. I have been asked by a couple forum members via email on help to convert tanks and vehicles to other countries versions or different paint schemes. Alas, I did the IDF conversions for Zach as he's both a friend and client (see his 12' USS Bunker hill dio on the John Jenkins forum) and like Andy and his crew I'm trying to finish my VN dioramas and several client projects for the Chicago show next month. Having said that, I'll outline my approach below and happy to answer any questions. It's not really difficult, especially if you have even basic modeling skills. Next to research, the most time consuming job is taping all the great detail K&C puts into their vehicles that won't change color like Windows, tires, equipment, etc. Us many small pieces of tape vs large ones that are hard to work with. I then mist 2 light sprays of grey or black (depending on the vehicle) auto primer over the taped up vehicle. letting each coat dry. I then use a technique most modelers use-I airbrush whats called pre shading over all panel lines, vehicle edges, and natural shadow areas, leaving the middle of panels that catch the most light with just the primer as show on this tank receiver.
I then lightly spray the base coat over the whole vehicle as seen below. Again a very light coat, the first of 3-4.
You don't want to completely cover the pre shading until the last coat so it is barely visible (in this case, this was a 2nd to last coat, as my final was a lighter version of the base color I used to keep it relatively tonal to the colors of Zachs K&C IDF vehicles-it doesn't have to be exactly perfect as all armies vehicles colors are always subject to variations.
Next is the **n part-Painting and weathering. Making a darker and lighter version I airbrush both the highlights (tops of vehicles and anywhere in direct light)and shadows (anywhere a natural shadow will fall). Incidentally, all these steps can be done with a brush, but If you're going to due quite a few, you can get a nice air brush and compressor set for about $200 on amazon that will give you much more of a professional look. The desert is brutal on vehicles, and maintenance vehicles especially get really beat up and dirty, and tank haulers are the worst as weight and tread really rip through paint to bare medal quickly. I used a fine tipped brush to create scratches and worn areas using a mix of dark paints along vehicle body edges, door edges. where crews walk, etc-look at lots of pictures for inspiration.
