John,

   I did a quick search about compatibility of PMMA (cladding on fibers) with 
chemicals,
in general it is not recommended to use alcohol and looks like at elevated T 
(during epoxy cure) it may be quite damaging (not clear what type of damages),

it is concerning, may be we should look at information from some other 
sources
