There is some paint on stuff that you can buy in the USA.
Basically like the stuff on the bottom of kids sleepers etc.
Sorry I don't remember its name. When I wanted it a few years ago, I found it in the USA, but not able to get it here in Canada, I just gave up hope on it. From what I remember, it was sold in Michaels and Home Depot stateside as a regular store item. So best to ask them!
Good Luck!
