Diving into the action of a 1921 Baldwin Hamilton upright, I found a nightmare of cracked and broken flanges, bent center pins, and broken jack springs. Man, I've probably replaced a handful of jack springs in past years, now I had about 12 in one piano. Sheesh. Anyway, most of the hammer pinning is okay, I think, in that I can apply Protek, swing them a dozen times, and then measure 5+ swings. But (and here I appeal to people who have used Protek in this manner) can I count on that to hold up, or will they tighten up again?
