You do not need the coating to desolve to get results. Send the page
back through the printer an extra time or two, printing nothing. Extra
fusing gets better toner/coating bond. A good ironing and the toner
sticks, and smooth slow peeling under water the coating will simply rip
at the edges of the traces. I'm peeling within 30 seconds of getting it
wet, slight softening of the coating but I'm not sure that's long enough
to think of it as disolving.
And you don't want it to disolve. Disolve and it comes away from the
paper as well as the traces, and that's why it leaves coating in the
holes and between close traces. You want it to peel well, and peel away
all the extra coating material, not disolve and leave coating on the
board. My own boards are far improved since viewing it this way..
