I just started using a fresh batch of resin/hardener from Aeropoxy

side. *I decided to uncover the part 30 hours after the lay up.

When I pulled the peel ply off quickly, the line where it separated
glowed bright purple for about 1/2 second. *I couldn't believe it, so
I went and got a couple witnesses and immediately they saw the ply
turn from dim white to bright purple too. * I proceeded to pull a
large section off very quickly and that lit up the section of peel ply
from underneath!

Has this ever happened to anyone else? *Any explanation how it could
even be possible?

We held the separation line up to the light and studied it when it was
perfectly still. *There wasn't the slightest bit of purple showing, as
it wasn't being ripped off. *The only explanation I can muster is, the
breaking of molecular cross-linking caused a temporary, chemical
reaction, that is not visible unless the epoxy is really fresh and the
surrounding light is not too bright.

no microballoons were used
