Assembling the models was a snap, as Battlefront provides assembly instructions. Even without the instructions it would have been easy, as the wheels could not be easily glued in the wrong place because the fittings are different shapes. The only piece that was tricky was the gun barrel. Getting this on would be a pain if you didn't have tweezers and some superglue accelerator. I got the accelerator I use at a local hobby shop that specializes in plastic kit models.
Once the glue was thoroughly dry (nothing destroys a brush faster than unset superglue, by the way), I primed the models black. There's a lot of opinions on what color makes the best primer, but for vehicles, I tend to use a lot of drybrushing and I find that black works best for that technique. I don't think most competition painters use black primer, but I find it works well, and gives you a nice-looking model without spending too much time painting.
Unlike a lot of folks, I brush-prime models - especially when they are 15mm-or-below in scale. Using an airbrush is a real pain for something as simple as priming, and I find that spraypainting the model has a tendency to leave gaps in the coverage that I end up brush-painting anyway.
