Davy, what do you consider the best product to use for dressing the fly line? I've heard of Armor-All, and I did use some Rain-X on an old line.
I've got some Scientific Angler Fly Line Dressing that I've used but wondered if there was something better. Usually just wash the line with a bit of liquid dishwasher detergent in warm water, rinse, dry, then apply the dressing. Is this the best method?
