Thanks for all the advice guys! Ya you would think the extra layer of glass would add some weight but it's actually relatively light (must be the epoxy).
So after asking for advice I got impatient and ended up going to the hardware store, buying some polyurethane, and using it for the repair. Might have been a stupid move but we'll see how it works out. I removed the delaminated area with an exacto, sanded it up, cleaned the surface with paint thinner, and used a foam brush to apply a thin layer and push it into all the cracks. I'll probably be sanding lightly and applying a second coat tonight, and maybe another the following day if necessary. This might end up being a lesson in what not to do, but it only cost $15 so here goes nothing...attached some pics below!
