I read somewhere on here that someone was going to used pvc for their roosts with non slip on the top. This got me to thinking a bit, how to create a non slip surface without "sticking" something to it. My though is to use either the under coat for vehicles that sprays on or bed liner spray on. You can buy them both in spray cans. I think that if you rough up the surface of the PVC and spray this stuff on, it would stick pretty well. Would they peck it off and eat it? Or would it stick well enough to not come off? Tell me, good idea or bad idea???
