I paint wood and plastic structures using a brush and mostly with acrylic paints that clean up with water. I don't apply primer to wood structures because I think they look better when the wood texture can be seen. That's why I'm careful about bracing.
I use "Titebond II" yellow carpenter's glue for basswood models, Testor's styrene cement (in a tube) for plastic models, and epoxy (half-hour working-time) for metal-to-wood. I don't use CA or rapid-drying adhesives. I prefer to have extra working-time, set the parts into exact position, and then take a break to let the glue dry. Yellow carpenter's glue dries in about two hours and creates a strong bond.
Every part is test-fitted multiple times before I apply glue and attach it to the model. Even laser-cut parts need the edges cleaned-up by filing or sanding to remove the nubs that hold them to the wood sheet. And parts that need to be cut with a hobby knife (I prefer a single-edge razor blade or razor saw) need to be "trued up" to be square and have flat edges. I sand the edges of large parts by laying a piece of sandpaper on the workbench and moving the part over the sandpaper to straighten the edge.
