Haven't used that.

I do use laser printer paper or paper towel between the iron and the
papers I do use.

30-40 seconds, I think?  Also pre-heat the PCB for 10 seconds or so.  (I
sorta have to be there, sorta do it experientially not by timer.  Been
reworking the computer room for the last week, still much to do, then
I'll get back to board making.)

Usually <G>

If you peel, you lose traces - go do something else for 10 minutes and
"slosh" the water a little when you come back, it'll be free by then.

I do 2 over-sized pieces of paper - line them up and tape or staple them
to each other, sandwiching the PCB between them.  Then I iron one side
on, flip and iron the other side.

Try this: Make a test slip or 3 with some "spare" parts of your film and
experiment on some scrap PCB bits - get your settings right with those,
you'll prefer not messing up your master PCB film (little 1" square
fragment of film can tell you a LOT about what works with YOUR iron at
YOUR settings!)

Oh.  And get rid of the water in your "Steam iron" if any, before
starting <G>  That won't help at all.

Good way to go!
