Slightly off topic, but I have to share. I have a large darkroom "spillyway," i.e., not a sink that can hold water but a long trough made of wood where I put my trays for printing. It is covered with water resistant paint and last summer, I wanted to make it a little more water resistant so I bought some very serious marine paint. When it came time to do the job, I read the instructions which pointed out that this paint was pretty nasty stuff and should be used only in an extremely well-ventilated environment. Hmmmmm, I thought. My darkroom is ventilated but ... Anyway, I called the manufacturer and told this young guy on the line my situation. He replied, and I am not kidding:
"You really need to use this like it says, in a well-ventilated place like ... the OCEAN."
