Toilet lid!

[abnormalsanon.livejournal.com]

I've been hoping to decorate a toilet lid to go with the 60s pulp fiction theme I've got going in my bathroom. I was thinking of putting some paper images on it and putting a few layers acrylic spray over it to seal it. Two questions for you:

1. Has anyone ever done something like this before, and if so, do you have any hints to share?

2. If acrylic spray is indeed the way to go on this project, can you recommend a particular brand? It needs to be waterproof (obviously!) and fairly durable stuff that won't chip horribly.

Thanks :)
