Brs,
   What is the likelihood that the woven glass cloth had some spots/areas which did not accept the treatment process.   I believe that the term for this is resin recession, non-wetting.   Is it possible that this anomaly could cause an exothermic event to occur?
Victor,

Hi Victor,

Treatments for the different resin types are typically applied by the glass fiber/glass cloth manufacturer.
