Spray for polyester fiberfill?
I am working on a project using polyester fiberfill. The fiberfill will be on the outside of the material so I'm trying to find something that I can spray onto it to harden it and protect it so it keeps it's shape. I was told there was a spray in the automotive section in stores that might work, don't know what it would be. I was even wondering if paper matte spray might work. Any suggestions would be a huge help. Thanks.
