Hey the page of R.G. is interesting, didn't know that one.

He uses a pump to spray the etchant. too bad i didn't buy that all
glass/teflon chemical pump on ebay..
I have terminated the rotary etcher a while back due to various problems,
and it will be a while before i attempt a spray etcher again, but i'll
still be very interested to hear about your system.
Also, the photo-process stuff is sure interesting for many here, as it is
basically the same problems with PCBs you have/had to solve.
It will be great to read more about your setup, and i think there are
people here that know how to solve the bubble-problem with laminate.
