IMG_0090 seems to show delaminated glass. Anywhere the glass isn't bonded to the wood, it should be removed and replaced. The wood looks a bit starved - if it's not sound, perhaps some penetrating resin could be applied to firm it up, then a new coat of fiberglass cloth. It's a good idea to saturate the underlying wood with epoxy before applying the cloth to get a good bond, then apply the cloth and epoxy before the first coat has dried so that you get a chemical bond

Sand it back far further than you think, saturate the wood, saturate the glass cloth. Apply and cover with plastic wrap and smooth. You will still have to sand it a bit. I agree, it looks like it is getting water under the glass (which is just one reason why you shouldn't glass over wood boats IMO)

Thank you Tungsten, David, and Jerry for the responses.  Yes, you are correct that you are seeing delamination.  I'll sand it back further and try to get to un-delaminated spots and follow your recommendations.  

Related question...what's the best way to get around the corner?  Do I use chopped glass, or some type of joint fiberglass tape?  Assuming your answers to those questions, would I then do some finer/finishing glass, or something along  those lines?

Thanks again for your help!!!

Chopped glass has no strength so if you can find some tape that works best. Besides chopped glass is nasty to work with. If you can find it you can do some nice detail work with silicon micro balloons but again, it is mostly for filling and sanding. You can also use them as a base for your glass so you can flush it out but frankly, I'd just get some glass on it and go fishing. I have repaired boats that look far worse than this and they are still floating 30 years later.

Tape it is! Does it make sense to do a few layers of tape, and/or some actual cloth on top of the tape?

Biaxle tape. Like 45/45 does corners well. Also known as stitched glass. If not you’ll just have to cut reliefs in the regular glass. Heat your resin up prior to mixing this will make it like water and penetrate better into the wood prior to glass.
