I might try the vinyl.
I'm ladygwen's husband. If you're going to try the vinyl I'd recommend the long life type. Of what we carry, that would be Avery A9 CAST. That's the heaviest and most UV stable product and intended to have a color stable 9 year life. It comes in 15", 24", 30" and 48" widths and can be purchased by the yard. There are 126 colors to choose from with 19 of them being blue. We're using Vivid Blue on our tank.
If you want to buy from us we have a website located at www.vssusa.com
