get ready because you are in for a long haul my friend...
aside from the usual crowbar, chisel, screwdriver, etc...
the best tip i can give you is to get an oscilating saw... one of these bad boys
and use this tip
its basically a scraper. it's sharp enough to get inbehind the old wood and it'll vibrate it loose fairly easily. i tried an air chisel and all it did was make a TON of noise and vibrate the whole boat. once all of the old wood is out, sand it smooth down to the original glass
then glass it in all new!
