You said :
>I know this is a very small point but Scotch Removable Magic Tape is made by
3M.
Yes that's the stuff !
It's just that people tend to think of Scotch Tape as the high tack shiney
transparent stuff which rips paper to pieces when you try to pull it off again.
I also use the Magic tape as a resist in etching and it is far better than
masking tape if you are protecting areas of paper from sensitising solutions.
Good Stuff.
