I'm using the pianotech granulated plastic with half the solvent recommended to make double strength. For the shoulders. For the top I add twice the solvent recommended for a half dilution. I like to dose the shoulder then follow immediately with the dilute on the crown. It draws the stronger stuff up from the shoulder, while at the same time preventing it from entering the crown. This creates a gradiation of hardening. David Stanwood >Double strength juice is what? 4 to 1? 2 to 1. This is to >stiffen the low shoulders right? > >David Ilvedson, RPT >
