Depends on what is being glued. Rollers are awesome for quickly and evenly gluing broad surfaces, and also for tasks like gluing rims, as you showed me, Pete. They are fast. But with many things, the roller just isn't what I choose. Fingers work great. Brushes work. I keep a brush stuck in a plastic beverage container at a depth so that the bristles, and part of the ferrule are submerged in water (in the container). Low maintenance, and always ready. A 1/32" skip tooth trowel works great for laminating or veneering. For spreading epoxy to bond a fretboard to a neck, I use the mixing stick to strategically place some blobs, then the 1/32" skip tooth to evenly and thinly spread the epoxy. Very little squeeze out results. This is also how I glue headstock veneers. For bindings, a tiny squeeze bottle and the brush that lives in a water bottle. For bridges and braces, HHG from a squeeze bottle, and my precision glue spreader. In cases where I use my fingers, the glue is applied from a squeeze bottle first.
