I am wanting to try and do something creative with the liner under the hood of my Cruiser. After making Revenue Canada and the Provincial Pharmacare Happy for another year funds or reserve are at an all time low.

If I could get some assistance on the topics listed below I have a few ideas: Large decal of a ganster, or possibly a picture of Fearless Fosdick from Lil Abner, or maybe a poster of some nice quite old time city or town scene. Any help would be appreciated.
How water proof is it and is there a way of cleaning it?
Are both sides waterproof or do they have to be waterproofed?
How is the best way to try and remove those stupid push in plugs that hold it on so you can use them again or is that possible?
Is there some sort of clear matt or dull finish that could be sprayed on it to waterproof and prepare it? If so what would it be called and who would make or handle it.
Has anyone tried glueing a poster or pictures on it?
Many thanks for any advice.
