I think that your wet method will be very valuable for soldermask,
which is harder to adhere and process without bubbles or wrinkles than
photoresist. In fact, DuPont and ThinkTink make recommendations to
use "wet" methods improvements prior to laminate if problems arise,
specially when a vacuum laminator is not available (the common case in
hobby or small shops situations).
