About protecting and storing chips after decap

Some options:

• Tape over cavity: current standard practice. Use Kapton. When wrapped fully around is very strong
• Slide coverglass glued to top: probably a good long term solution. CA glue allows later removal
• Nail polish: dries slowly. Would need to be applied in thin layers. Otherwise, think its pretty inert?
• Hot glue: CTE might destroy bond wires
