The process that i use is this:

In step 5 i use boiled tap water, i leave the board there for about 30 min to cook the paper (make the fiber of the paper more soft), after that i just peel off the paper very very easy.
Here are some samples:
I've done many boards all with 100% success with that process.

Quite ok. Just that some are over etch.
Make sure when you expose the board over the UV, the overlay should be
sticking close to the board. This is to prevent the UV from entering those trace you want to preserve. If you use laser toner method, make sure you have good transfer. When etching, try to stir the agent against the board. This is to ensure the etching process is even throughout the board.
