I ordered N48 magnets from Ebay.
Glued them inside the facemask, 5 at top and 2 positioned
inside the forehead.
When the glue had set, I simply put on the magnets outside
of thefacemask (using the magnetism).
Then I put some glue on all of them and placed the dome in
place. I then spent about 2 hours holding the dome in place
while the glue set.
To make sure not to scratch the flaceplate more than neccesary,
I added filt pads (the ones you can add under chair legs etc,
on the magnets inside the dome.
Final result. I can easily put on and take off the dome by myself,
top first and then forehead. And it really stays in place!
