Painting by Immersion and by Compressed Air: A Practical Handbook

First published in 1915, this pioneering handbook documents a technological revolution in industrial finishing. Arthur Seymour Jennings makes the case for compressed air spraying and immersion dipping as the future of paint application, arguing that these mechanical methods outperform traditional brushwork in speed, coverage, and cost. The book walks manufacturers through the practical advantages: paint reaches crevices brushes cannot, multiple coats dry faster, and labor costs plummet. Jennings draws examples from the automotive and agricultural equipment industries, where the pressure to scale production demanded new solutions. What gives this century-old manual its strange charm is the urgency in its prose. The author writes as though the entire manufacturing world is on the cusp of transformation, and in many ways, it was. For historians of industrial technology, this is a snapshot of American and British manufacturing at the exact moment when mechanization reshaped every surface. For restorers and preservationists, it offers insight into the materials and methods used on early automobiles and farm machinery.
