Spin Coating 30x40"
I've heard from John Preston that he used to spin coat very large sheets (perhaps vacuumed down acetate?). The sheets were about 30x40". They were coated with a silver halide gelatin photo emulsion and used for map making somehow. He says they got good even coatings, so I guess it can be done even on a very large scale.
