Your local sign shop should have some or a similar product. They may not sell it to you though, you only need a few oz. A sign supply store will sell it to you but unless you are a sign shop you will pay a lot more than you should.

You can try contacting "The Sign Syndicate" out in San Diego (858) 880-1400. Eric might be able to help you.

That may be your best bet.

If you can't just pull the sticker off a little bit of this at the top edge allowed to sit then scrape down to expose a little more of behind the sticker and slowly work your way down.
