Has anyone disassembled a plastic framed hatch. I am having to replace the frame on a Gray/Pompanette hatch. The PO used a silicone sealant which is stuck on the frame like epoxy but never adhered to the boat. Pompanette will sell only the frame for a lot less than the hatch. The hinge pins are staked into the hatch lid and of course one came out easily and the other is not cooperating with my drift pin and hammer. Heat? Any ideas?
