I've used the static whiteboard paper. It's brilliant and sticks/ clings (but wrinkle free) to the walls of your house and wipes clean. Plus you can move it round the house. It is expensive - someone gave me some sheets when I was delivering training.
Can't help with the melamine paint but I saw a roll of whiteboards in Rymans which use static to stick. In the description it says you use them on a whiteboard stand but the packaging implies you can use them anywhere! It might be worth a look. Quite expensive but you might find other people who would be willing to share a pack with you.
