: Are the fibers exposed on the surface or are they fully
: encapsulated in the epoxy/varnish. If the fibers are exposed, it
: means someone sanded into the glass. If they're encapsulated, it
: means the glass wasn't properly wet out and is probably
: delaminating from the wood. Either way, the glass will need to
: be replaced, but as Paul said, it can wait until the end of the
: season. However, I would cover exposed fibers - if there are any
: - with a coat of varnish to prevent the problem from getting
: worse.

From the next pic it appears the material is well sealed and varnished already I'd just leave it alone for now. Of course there are some people think that a few more coats of varnish will always be useful. ;)
