With a vertical, I tip the piano back, but do not turn out pins or remove action. I tip the piano back, and just squirt away (using care to not be sloppy), putting as much at the base of the pin as will soak in. If I am doing all pins (not always is this the case), I will use between one and three of the little (4 oz.?) bottles of the thin CA glue. I have done this to perhaps ten or more pianos, and all but two have had great results. Two were a bit improved, but still were not great. Bottom line: good option under the right conditions.
