I've seen lots of comments and such on doing umbrella's and those kinds of items; but can't find any info for doing either the foldable aluminum covered cardboard (probably not) or more specifically those foldable nylon (guess that's what made from) ones. RPL has started selling some sub-able window models; but they have no idea about windshield versions. Have a client who want to do some for their sales; but if it's foldable / bendable - then screen print or decals would not last long before cracking and crumbling would they.
