Propionate is shipped in dry pellet form. It dissolves in acetone or virgin lacquer thinner to form a waterproof base for dipping and sealing soft lure woods, like Balsa and Bass Wood. Once it is dissolved, the chemical will then penetrate the wood grain and raise it after the first dip or soak, it will dry quickly between your dips. This allows you to get your painting done in less time. Once the lure wood is treated with the Propionate, it will then strengthen the soft woods enough for sanding without adding any significant weight to the lure overall. Here is a quick set of handy instructions that will explain exactly how to use this additive. Note: Always, always follow the recommended safety precautions when you are handling chemicals, including the use of protective eyewear.
