I used the scraping method last night, to some good effect. Unfortunately wood didn't work at all, and plastic only worked once I got it down a bit, so I had to use a metal paint scraper to *carefully* remove the top layer, and then as I got closer to the plastic, I was able to switch to the plastic scaper. Of course, it took me about an hour to remove two 1 inch squares of the stuff, so this is going to be a long process. As predicted, the case is unyellowed under the adhesive residue, so there's a batch of lumpybright in its future.
