: Hi Don. It's worth talking about. But, if the glass had been
: saturated, even rubbing down to the glass would not create any
: place for water to go, right? All the spaces between fibers
: would be filled with epoxy.

: BTW, here's a photo showing the same area, just after glassing.
: Aside from one wrinkle-caused flaw at sheer line (photo left),
: it's all perfect.

Actually it looks like the glass might have contaminates on it so it didn't wet out equally everywhere. Glass needs to be stored properly to prevent this. Not all suppliers store it properly either so it might not be something you've done.

It's not the glass itself btw, it's the sizing (coating) that allows the glass to properly bond with the epoxy. The other possibility is it was sized for polyester which isn't always totally conpatable with epoxy. Not all glass suppliers state which sizing the glass has in their ads and most builders don't know to ask.
