OK, so I had the bright idea of replacing the pitted and scratched windows on my '81 M15, and managed to get the port side window off without causing much damage to the boat or myself. But whatever caulking was used to seal the plexiglas (or whatever) into the hole is really wicked stuff. I've scraped at it with a putty knife and removed some of it, but I'm afraid I'm going to chew up the fiberglass if I continue along that path. The caulking is still fairly soft, but it sure doesn't want to come off easily. Does anyone know what was used to seal in the windows back then, and what I might use to remove the caulking other than carefully applied elbow grease?
