I agree with the bulk of that, However, around the turn of the century a lure by the leading bait company were around a dollar some even more. Considering that people were making a dollar a day a fishing lure was a major expenditure. Baits that were produced in that era were built with quality and intended to last, due to expense. The majority of lures were dipped in enamel paint to provide a prime and base coat, which upon the colors were applied then dipped in clear. I am not sure how much impact dipping a lure in a sealer would effect the overall cost at that time.But if doing so would allow skipping a one or two of the dips in the enamel. Would it cost more or less?
