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
