Therefore they will have poor and unpredictable aging 
characteristics.  The one thing I can guarrantee is that the 
resulting film will not remain the same for very long perhaps a 
matter of weeks, but certainly only months depending upon the keeping 
or exhibiting environment.  Some decades ago, hairspray were 
experimented with to "fix" sensitive and friable surfaces such as 
some types of pastel artworks.  Physically a success but they soon 
aged badly and were ruined.
