From the description given, my guess (and that is all it is) Steve is talking about coating plates with one of the emulsions light Liquid Light or something like it. If so then he would be either contact printing or using an enlarger to expose the plates - Is that correct Steve?
Even this way, I would not expect the plates to take more than two days to dry - even in Houston. As Bill mentioned I think someone here can help, but more information is needed. It's just too hard to troubleshoot from the information given thus far.
