Make a citric acid pickle, with 3oz citric acid, 1lb salt, and 1oz Lipa-Solve 77, per gallon of 85 deg(F) water. Leave in for 2 days, and stir often.(this is all under the assumption that you have thinned it well with a shaving machine)
Pull and drain for 3hrs, then neutralise the skin. Neutralisation= 2oz baking soda, 1/4lb salt, per gallon of 85deg water, for 45min. Pull skin, quickly rinse with a hose, then drain for 3 more hrs, in a well ventilated area.
Apply a liberal coat of TruBond 1000B, and follow the finishing directions.
