Homebrew PCBs

I've been following this thread for a while now and it has intrigued 
me enough to sacrifice a Lexmark Z52 printer to convert it to a 
straight through printer.

The major issues (IMHO) is in finding a resist that will: 1. flow 
through the printhead, 2. wet out and print well on the copper 
surface, and 3. will not be removed by the etchant.

After a visit to my dentist getting my teeth sealed yesterday, I 
started thinking about uv-curable inks. In other words, a 2-step 
process, printing the resist and then curing it.

I thought about getting some of the tooth sealer to try, but I 
realised I was missing the obvious. We already have uv curable 
fluids used for pcb making - the photoresists. I had used a couple 
of time years ago and didn't get the results hoped for. I had used 
the spray cans of resist to sensitize the boards. 

I remember seeing on the web (forgot the link), a range of pcb 
making chemical that were sold in apllicator bottles, like liquid 
shoe polish. Has anyone used these? Any thoughts?
