me too. a full can vaporised through the CLOSED LID!
and the skin absorbs it and it is toxic (like everything, i know).
it also vaporises much quicker than laquer thinner, which is no advantage.

pressure repeatable... well, a laminator did the trick for some.
if you want i test the copier fuser i have if it works as well.
It is pretty predictable with the iron for me now, maybe a few boards
practice does the trick for you?

For me the "experience" wasn't that good, i was used to making the boards
with a tedious photo process, but i very like that it is so much easier 
now.
