My original plan was to make the vehicle one of the ones in my old unit, 4/20 FA. It was one of the last FA units in the US Army Reserve before all combat arms units in the Reserve Component were allocated strictly to the Army National Guard. I was Bn XO at the time and our vehicles were in NATO 3 color. Unfortunately, I never took any pictures of any of our vehicles except my own, or perhaps I might not have made this blunder.
While painting overall sand would certainly be easier, regardless of what re-painting I attempt, I'm pretty much locked into a major disassembly because of all the detail items on the exterior, and having to get the underhull/suspension painted. And airbrushing the front glacis needs to be done without the blade which is now secured to the winch frame and hydraulic cylinders. Even the boom is pretty much impossible to take off now that the hinge pins are inserted.
Masking with all this stuff is out of the question, and as I discovered during final assembly, even handling the model to add details can cause damage to some of the detail parts if you're not paying attention to how you hold it.
Right now I think I'm simply going to put this one into a box on a bottom shelf in the basement and move on to other projects. I've been working on this project for such a long time, I just don't think I'm ready to jump back in to a major overhaul on it right now. Maybe after I've completed some of the other projects on my workbench, I'll find the enthusiasm to re-tackle this.
But I'm proposing a corollary to the old carpenter's rule.
