It was absolutely fine. Put a couple of fine coats on and it lasted well, I had it in some IKEA cabinets that I used in the kitchen for a couple of years, then as bathroom cabinets for a few more. It's probably not up to having items scuffing up against it too much, but I had no problems at all save the odd small scratch.
I think it's Plasticote or something like that - it's in the section with all the metal sprays, silver craft spray, stone-effect stuff, that sort of thing. Don't think I still have it but have something else from same/similar range so will check next time in garage.
Fairly easy, easy instructions, you just need a steady hand and sharp knife. Its on my window, sometimes I peel a small corner back to peek out accross garden to see if my kids are ok and it still sticks back on as before.
