I have been fascinated by DIY japanning recipes ever since watching a video on Hand Tool Rescue where Eric mixed up and applied some to a restoration job. For those who may not know, japanning is a thick black lacquer finish that is often used to protect the metal on tools like sewing machines, hand planes, and other small tools.
In this video, Eric shows the results of some experiments he’s done with recipes for a spray-on japanning. The recipe he ended up with was 60% turpentine, 25% asphaltum, and 15% boiled linseed oil.
Because of the thickness of the mixture, he uses a special spray bottle for thick liquids that he found at McMaster-Carr. He also tries applying it with a refillable pressurized spray can.
