Trying to make myself a little kit for future SEs, but I wasn't quite sure what people often use when doing a proper sealed box method.

The tool: I heard those plastic blades used on Rubik cubes are quite good at safely removing a sticker without damage? Any other recommendations?
Removal: anyone using anything special here? I know some people do it with a hairdryer but are there any useful substances that could be applied instead?
Reapplying / Regluing: what kind of glue is the best for this? I don't think a 1$ glue stick is gonna cut it...
