I was getting ready to load film finally today and noticed something about the holders. The area around the flap and light baffle is not painted black, just plain unpainted wood. I can't find the article, but I think it was in View Camera a year or two ago, that the author suggested that painting the area around the baffle and flap is a good way to cut down on light leaks. To me thats rather important given the cost of importing ULF film from the US.
Any ideas as to what paint would be best to use for the holder? Is it really necessary with new holders?
