Decoupageing a Bathroom Wall

Hey there, everyone. Well, I'm about to be in between jobs and during
my time off I'm looking to complete a project that I've been thinking
about for a while. Basically, I want to use a lot of art work and
photographs that my friends have taken and decoupage them to fill up
my entire bathroom wall.

I'm looking to create a great big collage, basically, but one that
will be able to stand up to the wear and tear that a bathroom wall
normally goes through (the thing I'm thinking of most is steam when we
take our showers... I don't want anything to peel).

I've looked at a product called "Liquid Glass" that certainly provides
the kind of finish that I'd most like to see (the way the "glass"
reflects light is rather nice and gives whatever it's treating a good
varnish/shine).

But I'm curious if anyone out there has ever tried anything like this
before and what their recommendations would be as far as what to best
use to (a) attach the art to the wall and then (b) to coat/seal it
effectively. Any tips would be most appreciated. Many thanks in
advance!

As in "automobile and boat polish?" Or are you
referring to 'sodium silicate?'

a) attach the art to the wall

You give no information on what the current
wall surface is like, so how can anyone answer?
Makes a huge difference whether it's the usual
sprayed plaster finish (roughness) or a perfectly
smooth surface.
