How to treat corners of Vinyl CP cover?

[JoshuaMiller]

Hey, guys-

I'm planning to cover the bottom sides of the box that makes up the control panel with Happ black adhesive vinyl.  I'm planning to do a sort of half-hexagon shape for this.  I realize that I can slightly round the corners and stretch the vinyl around, but there will have to be seams on some of the corner edges.

I have seen a sort of plastic strip that covers these seams, but cannot seem to find anywhere to buy this material.

Does anyone know where I might find it (and what it's called!)

Thanks-
