Probably will be fine with lam and a higher quality vinyl.
If you have that metallized polyester stuff (believe RTape EFX, and a few other names), it'll want to curl when printed to the edge and is a beast to print on without a nice blank space. I have however cut out of metallized polyester and then cut an outline out of black separately and overlapped it with good results.
Also, keep in mind that the inks have a transparency associated with them and depending on what you're printing overtop of, the black may not be as rich as you want due to the blending.
