The glue is good, the latex is good.  The glue 
sticks wonderfully to the latex.   However I did 
not make the fiberglass piece I'm trying to bond 
to.  So it has some mystery ingredients....  I 
wonder if it might have been made with polyester 
resin instead of epoxy?   We are guessing that 
it's probably some kind of reaction from the 
fiberglass chemist mixing with the contact 
cements...causing them not to bond.  Perhaps a 
polyester resin that didn't completely cure correctly.

I need ideas for what I could do to seal the 
fiberglass so I can bond to it with the contact 
cement.   I'll probably have to strip all the 
glue off, sand it down a bit, seal it with 
something that will not interact with the resins in the glass.

Any ideas?
