LG's Hi-Cal brand black looks to be a good match in sheen. Joe here in Phoenix was showing me some he bought from a supplier and that was the brand of sign vinyl they were selling. For an outdoor sign the stuff is horrible, if you look at it too long the glue falls off the back of the vinyl , but for indoors it should be fine. That is what I'm going to buy to redo mine when I get around to it. If you don't want to buy a whole roll call around to some of the sign companies inyour area and see if thet have any 48" rolls of it they will sell you a secition from. Arlon may also be good but I've never compaired it to my machine.
