unkes60 0 Posted April 1, 2008 I have a cleint that specifically wants some sort of plastic for a substrate.The signs need to be 8 1/2" x11". And they need to be durable enough to be outdoors and posted on a sign post with holes at the top and bottom. So I'm thinking, not coroplast. Help?! I have been looking around for hours and all I can find is expanded PVC that supposedly is not good for outdoor singage. Any suggestions? Share this post Link to post Share on other sites
