Homebrew PCBs

Bob,

Do I understand correctly that this process does not include a drying step? With other processes I believe you apply the liquid, dry it in an oven, and then expose it with the artwork. It sounds like the problem you are having is dealing with the wet liquid. Wonder what would happen if you let it dry first? Would it still develop under the UV?
