Your best bet is to use cast film. Most short-term vinyl will dry out in 5-6 years and be difficult to remove. In addition, many short-term vinyl products us more adhesive to counter-act peeling and curling due to shrinkage and movement.
There are products designed for short term use (less than one year), often monomeric, and depending on the formulation are designed to be easy to remove. BUSmark 5800 comes to mind.
