Protective Coating?

[arewar.livejournal.com]

I want to print out some pictures and make a collage for a cover to something I'm doing. Since I'll be printing them out, they'll be on normal paper, and I don't know how to protect it to keep it from pealing off or getting wet.

Is there any type of paint or special plastic(-ish) stuff that I can put over the cover to protect it so it will last?

Bonus points for stuff I could make at home or find around the house.


Thanks so much!
