Yes, the bathtub stuff ;-) (I used the transparent acetic acid stuff)

I do exactly as you say and scrape it as thin as possible. I try to keep  
the surface glossy (if you scrape very hard it becomes dull as the paper  
is exposed, but i don't know if that harms.)
If you don't go to the edges of the paper it is easier (no mess on table)  
and i rarely have a pcb that fills the sheet.

I will make pictures at some point, perhaps, but they won't say too much i  
think.

Possible effects on the printer, well, if it is cured i would not expect  
any.
it does not come off easily, and it does not melt, and it is very soft, so  
i can't see why it might damage the printer.
