Update: 90% isopropyl works way better than 50%
I'll post some pictures later, but it removed the glue almost as well as the acetone and didnt touch the symbols
Guess I wont be needing that goo gone
As for a fish knife, I dont have one of those but I have been using some clay carving tools with a similar tapered edge for scraping when my fingernail starts to hurt, and they work great. The only problem is certain areas are hard to reach, especially with the rearing pose. But that's what fingernails are for.
